Quoted from Haymaker:
Worth noting that many (most) QD sprays are silicone based.
Its been a while since I checked in here, but since I've been hardcore into the automotive detailing scene again, I can't believe how many awesome products that are on the market now. Carnuba based waxes are very old school nowadays (but still have a place). I want to ask vid1900 again if he's experimented with SiO2 based ceramic coatings on pinball machines yet and if he had anything to report. Theres also several other products I am interested in such as liquid sealants, which are much more durable than carnuba, easier to apply and WAY easier to remove than carnuba, and last a lot longer while still delivering amazing gloss and protection. There's even some sprays such as turtle wax seal n shine that have me wondering if theres a better way than the old way. Just wondering if you've had a chance to experiment with any of the exciting products that have made their way to the auto market the past couple years. If you'd like some specific recommendations let me know. I realize good for automotive doesn't necessarily translate to good for pinball, but there should be some overlap.
The problems with modern ceramic coatings and polymers is that they are difficult to renew. And some are difficult to apply.
They just are not designed for having a heavy steel ball grind fine metal fillings into them.
Once applied they stay put, black flings, ball tracks and everything else.
As an example, Full playfield mylar has been available for decades, it's very durable but It's impossible to renew.
Carnauba is hard enough and plenty durable, yet can easily be stripped of with naptha and reapplied. You just have to rewax every so often to clean off the metal filings.
It's not so much about the durability of the coating as it is about being able to renew it.
