I've painted a few things now and it it's dry but if I rub my finger on it a bunch comes off.. Happened with a couple brands now and I'd like to repaint my gas tank (it's black and so is the whole underside of the at now) but if it basically rubs off what's wrong with it? It's never rubbed right down just almost like it's the top layer, just curious before I paint it.. Or i Might just coat it with rust billet or something.
What temperature are you spraying? I think it needs to be above 65 degrees to use aerosol paint. Anything colder makes a mess
I've had that happen before. I forget which brands do it and which don't. Spray a coat of aerosol clear over it.
i'll look and see what i can get for the weekend. hopefully i can get the cast coat style maybe it was pretty warm..we had all the heat running and i was in a T-shirt and very warm..we sprayed the chevelle with a coat of primer and it dried in perfect time with no issues..almost too warm probably.
you may want to strip it before repainting it. the new paint may not stick to the rubbing off silver...
Not sure but it sounds like it may be a matter of poor prep. I've used argent for years and never had any problems with it.
i use a wax/grease remover prior to painting..there was no reactions from grease/oils just makes my fingers silver.. one brand was varsol? other was plasti-kote, and i used another brand they carry as well and had the same problem before..
a few possibilities here. old paint(even if the paint is recently purchased?.. it can sit in warehouses or vendor shelves for quite some time). Best to buy from vendors with stocks that are sold and replaced more often. not mixed properly. Old paint.. and as mentioned above it's usually best to assume that it may be older than imagined.. is tougher to mix and often warming in hot water/shaking for extended periods of time will help considerably to bring its "clear" back into proper suspension. use of high-temp paints or those which are more "chrome-like" can cause those special additives and metallic frit's to lie on top more than others which have clears to settle on top for added looks and protective qualities.
Are you sanding the surface prior to pain application? If not the paint will only adhere for a short while if at all.
There seems to be a mis-communication here. Everyone is pointing out preparation and adhesion. The op didn't say the paint was not adhering to the surface it was sprayed onto. He is saying the paint is staying on but if he rubs it with his hand some color will be left on his fingers. I know exactly what he's talking about because I've experienced it myself. It's like the metallic is laying on the surface and transfers to whatever touches it. It's pretty annoying because it looks good and it sticks good but when you rub it it ruins the look. It doesn't come completely off like it isn't sticking to the surface it was sprayed onto. This is why I suggested some aerosol clear to seal the surface. It's worked for me in the past.
You absolutely hit the nail on the head there, when I tried to clear coat a couple parts it changed the look of it and almost gave it a wrinkle-ish looking effect. Then I removed it all and painted them grey.
