I apologize if this topic has already been covered thoroughly in this thread or others. Does anyone have a method for laying SprayMax 2k on overlays? I read one post on applying around 5 coats of unspecified automotive clear, 30 minutes apart, with 1st and/or second being light coats. Does light coat mean a once over misting? I'm nervous about burning through a brand new vinyl overlay.

Thanks!

Thanks pinballinreno! This sounds like excellent advice. Patience is the biggest takeaway from this advice.

Now, after reading all the posts on ventilation and ventilators, I'm having difficulty finding a full mask with compatible ov/n95 cartridges. Can anyone recommend what they've used while applying spraymax 2k? Any links for a specific mask with the ov/n95 cartridges? I want to, at the very least, follow bare minimum ventilator requirements, replacing cartridges every 30 minutes. I'm planning to build the cheap spray room using pvc with cutouts in plastic sheet for air filters and box fans.

That's a nice option, Boslaw. I like how it eliminates the need for those filters while providing fresh air when used properly. Very nice alternative. Thank you!

Good info, BJM-Maxx. I only have a small red Harbor Freight Husky "hotdog" compressor that I use for filling tires. I can't remember the size or psi. This will require more research on my part.

Good info. I have an interesting layout with my garage detached, facing a shared alleyway. Front of house faces opposite direction, on the main street. A covered breezeway through the yard connects the back of house to back of garage. I'm debating whether I should spray this stuff outdoors, or just do the ventilation setup in my garage. Thanks for all the advice. I'll check out the volcano thread for more info. I'm definitely leaning toward spraymax 2k versus having a pro (or body shop) do the clear for me.

I really like the outdoor idea. Timing will be key. So much bright green pollen now through April. Then, super hot and humid summer.

Thanks to everyone for the excellent advice. I respect everyone's methods because you know what works for you. I've decided to play it a little safe while getting the less pricey full face respirator. Hopefully the air system is compatible with this mask. I still like the idea of spraying outdoors, underneath a cheap tent. The mask and air supply system will need to be tested prior to spray day.

Update to this post: Just received an email from Harbor Freight advertising al their oil-free compressors. Either I'm more aware of the terminology or they're spying on my data.

Thanks!

Fyi for everyone - The attached compressor is what I was planning to use. If you all think this is an unsafe compressor for air supply purposes, please share your thoughts. From previous conversation, there was mention of an oil free air compressor.

Hey Guys,

I finally got my DE Batman overlay. I just sanded away all the original artwork and cleaned the bare playfield. I want to start sealing the bare playfield with Spraymax 2K prior to installing my overlay. I understand that the clear will need to outgass for possibly 2 or more months. My plan is to spray the playfield outdoors, then transport to my garage, and keep inside a spray tent. Is there a minimum amount of time I should allow the spraymax clear to dry prior to moving into my garage? The reason I ask is for safety purposes. I wasn't sure if keeping the playfield in my garage would lead to an unsafe accumulation of toxic particles. I'm just trying to figure out if I should keep cars and family members outside of the garage for a certain period of time.

Thanks!

You have to pay me extra for that footage. Yes, she would go crazy if I told her to park outside for that long. I need to think this one through a bit longer.

Well, I guess I don't need to use Spraymax for sealing the wood...but I already bought 4 cans. They need to be put to good use.

Yeah, I'm using 2K on the overlay.

I went ahead and spraymaxed my bare playfield using several coats. I'm going to let it set for a week before sanding. I'll probably wait 6 to 8 weeks to install my Batman overlay.

Question for you guys:
This overlay has a clear protective layer on top. Will this cause issues with Spraymax adhering to the surface, or will several light coats work? I'm wondering if the ink needs to be exposed for better clear adhesion. I appreciate your feedback!

I have another overlay without the clear vinyl covering. Ink is UV based, so should be good. I'll keep the other one as backup in case I screw this one up.

Yeah, and I think it's a combination of the ink thickness and clear vinyl covering. The other version I have is here in the closeup pic.

Interesting. I was seriously thinking of installing the one with the clear vinyl film, then add a playfield protector...but I've read some posts that scare me into using clear. I wouldn't say it's mylar, but it does offer some protection...not mylar tough.

Good advice. I agree.

Ugh, I see little raised spots or bubbles after waiting 4 days from spraying 2k on my bare playfield. I probably sprayed too close, or had it in the wrong environment. Hope I can wet sand and buff this surface to smooth.

It's about 4 applications over 2 hours, 30 minutes in between applications (layers or passes could be 20+), or 1 can. I already smoothed it out. Probably too many layers for this step.
I went ahead and wet sanded, followed by naptha, novus 2, and naptha again. Feels super smooth now. I'm still having difficulty polishing these 3 green inserts to a nice shine.

Yes, they were sanded up to 600 grit prior to clear coat. I started with 220 and worked up to 600. The inserts looked clean and shiny prior to wet sanding.

Thanks for the helpful information. I'll just keep an eye on the clear and see what happens in the next month and a half.

Thanks for the info. I read so many different timelines and steps involved with clearcoating a playfield. No, I didn't block sand between coats in that 2-hr timeframe. That could be one of the reasons why those inserts are looking off. Great info guys. Keep it coming!

Ok guys, getting anxious to install my overlay to the spraymaxed playfield. I have to ask for your feedback on outside/garage temperatures during the clearcoat process. I read that keeping the clearcoated playfield in a 70 to 90 degree range is needed. Now that we're getting into the North Carolina summer, I'm questioning whether I should wait until Fall before applying the final spraymax 2k on my overlay. Another issue I worry about is the actual overlay and any additional heat and humidity. Have any of you guys been in this situation, attempting to spray in the nasty heat and humidity of the southeast? I have a feeling that waiting for more ideal temps and humidty will be the overwhelming answer to my situation.

Thanks!

I guess a window A/C is possible. Yeah, dealing with the humidity sounds risky to me. Thanks for the feedback, PinballAir.

Thanks PinballAir!

Guys,

Last weekend, I wet sanded and used naptha before applying the last 2 coats of spraymax. This was following the previous weekend's initial spraymax coats. So, I may have sprayed too close (5") to playfield based on a few comments regarding a better or smoother finish. That couldn't have been further from the truth for my situation. The orange peel looks even worse...or maybe there is some contaminants that I accidentally sprayed over? Anyways, my goal is just to do the best with what I have since I'm out of clear. In your opinions, should I wet sand soon (like today or tomorrow) before letting this clear set for the next 6 to 8 weeks? It's been 6 days since the last coat was applied. Either way, should I wet sand and polish once the 6 to 8 (maybe even 12) weeks pass? I probably should not have cleared a second weekend in a row but this is my first clearcoat project, and with an overlay. I appreciate all your feedback!

I bet the rag I used to clean with naptha was contaminated with something...maybe novus 2 or something else used in the past. That has to be the issue. Ugh...back to sanding this crap down and seeing what's left. I appreciate the support, everyone.

Edit: Deleted entire post on question related to time-frame for bringing spraymax 2k cleared playfield into home. I'm going to contact spraymax and post any info I receive.

Spoke to the Spraymax representative in my area. He didn't have exact numbers or figures to reference, but he felt 7 days after polishing/finishing would be safe to use the item (to put back into service). Now, he referred to marine projects, so this may not apply 100%...but he felt based on his 30+ years of experience that the effects of outgassing would be minimal. Just passing this info along. Whatever anyone decides on this issue, please be safe. I'm going to wait another week or two before bringing my playfield inside (once cut/polished).

Since this is my practice playfield, I'll probably wait a few more weeks before polishing. I know this stuff shrinks back and I should probably wait 12 weeks to cure, but I'm at the point where this thing needs to be installed so that I can test all the other parts. My spare playfield will be a future project, and will allow me to swap and redo this playfield. Also, having the spare to perfect will keep me from waiting to test, play, and enjoy this machine. I've already created a planned installation process and it should be pretty straightforward with all the advice and pics from other owners. I'm just looking forward to getting this pin ready to play.
