Quoted from pinballinreno:
It has to do the the thin edge where the ball meet the rounded wire.
Lots of wear in exacty the same area over and over again on the wire.
It just peels paint right off.
Ah, I meant more on the cabinet. For the wireforms I am pretty sure I am going to get the plated ones. The only place I can see really being an issue is the lockbar where you hit it with jeans, rings or whatever and around the siderails/buttons. But I would think with an auto clear, a few coats, should be more than sufficient to protect for home use. Paints should arrive any day, just need to do some prep work and I am going to paint the lockbar underside with a few of the colors to see what looks best. Then I'll do the lockbar, legs, hinges, siderails and shooter housing in paint and clear. I'll redo the door in the speckled black gloss. I have to do the door anyhow because the coin mechs are all lira, reimport. Feeling pretty confident about this now that I just finished the auto clear on a playfield and it's tough. I did a motorcycle tank too, the only thing that would prevent gas from eating it up. Got some nice new ramps sitting here, got a vibrating tumbler for the metal work (doing my JP now, looks awesome) and just have to apply decals to the playfield. I am sort of considering clearing it now after the decals instead of the protector. I'm about 2/3 of the way there (just a bit more to remove from the playfield, as long as I can unplug all of the harnesses easy, JP was not easily possible, I can take it outside and spray it as is without removing any of the under playfield structures. Dang.. I might just do that now. I am afraid I'll be unhappy with the newton rings that the protectors seem to have. I think the clear would help to level out the decal edges too.
*Edit - I think this might be the color, ordering now. https://www.amazon.com/Rust-Oleum-7274830-Stops-Metallic-Antique/dp/B0009XB3HM/ref=sr_1_10

Also got a semi-matte to see how that looks, never used it before ebay.com link: itm and I think it might look good, sort of like Houdini
Also gonna clear the coin door with the Spray Max, it will be bulletproof.
