Paint not sticking to Royale Resin wheels...

[Fly-n-hi]

This has happened with just about every set of Royale Resin wheels.

First, I soak the parts in Fantastic Max Grease Cleaner by Johnson for a few hours and then clean the parts off with soapy water. Then I prime with Mr Resin Primer. Then I paint Mr Color Tire black over that. But when I cut out masking rings to paint the hubs the rings peel the paint off down to the bare resin. I do this same process with all resin parts including Brassin and Aires and I don't have any adhesion problems with those brands.

What is different about Royale Resin and what can I do to get adhesion? Would enamel paint stick better? Do I need a different cleaner? This is a shame because Royale Resin wheels are fantastic! Any help is appreciated!

I assume you also rinse them after washing with soap. Part of the problem may come from there if you have hard water, but the likely major cause requires three critical questions:

When you take them out of the package, is there a strong odor?

Can you describe the odor?

Does the odor persist (can you still smell it if you sniff the parts, or if you keep them in a closed container for a few hours?

Triarius, yes, I do rinse them thoroughly and scrub them with a tooth brush while rinsing them off to make sure that there is no residue in any of the crevices. And no, I've never detected any odors coming from the parts. Its strange. Like I said earlier this only happens with Royale Resin...not any other brands.

I have noticed, too, that the resin the RR parts use appears to be better quality...or at least it appears harder and glossier. So maybe it is because of the type of resin? I don't know.

Now I will admit that there is a recommended cleaner in the instruction that I have not used. I will try it next (its some automotive bleach I think) but it seems like these cleaners that I have been using should have done the trick.

Why not contact Royale Resin and see what they may have to offer in the way of a solution?

Better living through chemistry …

If Royale lists a preferred cleaner, they know the chemistry of their resin and release agents, so that will probably work best. In that regard, I've yet to find a polymer that Simple Green won't remove, given sufficient time, at least. Yes, even enamel paints and some epoxies, though there are much more efficient, though more noxious, ways to remove both.

I'm glad there is no strong or persistent odor. When that occurs, it usually means misproportioned resin. While that can sometimes be remedied, it's an absolute bear.

It may be worth trying Isopropyl Alcohol to clean the resin -I believe some mould release agents contain silicon, the residue of which may remove better with alcohol. Dunno what's in Fantastic Max, but it may be short of the one thing that works on this stuff...

Failing that, a really aggressive airbrush cleaner like Badger's Aerosol one is safe to use on PUR (it digests plastic like something in a bad Sci Fi movie!) -I used it to de-Alclad a resin F-16 exhaust I messed up.

HTH.

Thanks for the comments guys! I went to the auto store and found a bottle of the stuff that RR recommends. I'll try that before I do anything else and see how it works. That stuff is called Bleache-Wite for anyone interested. It looks like some kind of de greaser for white walled tires.

Bleche Wite is also a popular method for stripping chrome, FWIW. It can also chemically blacken white metal, apparently.

Apropos of nothing...
