Paint FAIL
What suggestions do you guys have for some aluminum hooks and steps that I'd like to stay painted black?
This summer I painted everything with some expensive Rustoleum that is supposed to stick to any type of metal or plastic, high temp, all that good stuff. Well, everything was holding up fine until it got to -25 here in Iowa and then the paint started to chip.
Any product that'll handle the abuse? Am I going to have to powder coat these? New cowprint pattern, its all the rage.

The cowprint pisses me off every time I look at it. Those hooks and steps used to look so nice. Grrrr

Lisa,
The secret is in the prep, not the paint.
If there's a store in town that supplies the body shops, ask them if they sell metal prep chemicals. You need a light phosphoric acid (yes, I know they're aluminum, or maybe even zinc!!) A quick bath in that, followed by a rinse of de-ionized water and dried, then primered with a chromate (if you can get it in your state), and only then a top-coat.
JASCO Prep-n-Prime is an example.
The guys at that store should be able to give directions for its use, and get you anything additional (like the primer) to make it work right.

I had to scuff up aluminum with a coarse grit sand paper, wash it, then use alcohol on it to ensure it's perfectly clean before painting it. The results were OK at best. You could take it off and bring it in to have it anodized.
Edit: Just saw what Pop posted. I think that's what my father does to paint parts he machines.

I have some little side marker lights that are actually plastic...and the paint is chipping off those too. Any suggestions there?
yep, run...run away. I'll have you know I am actually a pretty good cook....just not very compliant.
I'll cook when/if I want to, and whatever I damn well please.

Plastic is "chromed" by a metal deposition process in a vacuum.
If you've got lotsa' bucks for the equipment, you can re-finish yours, too, but I suspect it would be a LOT cheaper to just replace them.
Unless, of course, Cedar hasn't a good plastics plating facility and you want a new career!

The hooks, I'm not sure....they came on the truck, previous owner put them on. I will tell you, they're handy to have. I've used them a million times to strap stuff down. I'd like something I can paint black that'll stay black, if I could replace them with steel hooks that'd be fine too.

Just look those hooks up online and buy steel ones that are already powder coated. Aluminum is a PITA to paint. Or uninstall them and have them anodized. I don't think that Herculiner will stick any better to that aluminum unless you clean it like Pop said and it's a PITA. IMHO, Herculiner is meh.
