Prime, Base & Clearcoat trim

[Canuck]

I am currently doing a base -clear coat on my 74 bronco. I had a thought last night, has anyone ever tried to prime, and then base -clear their trim in another colour?? how did it look , how did it stick.......????

Painting chrome is generally not a good thing to do because adhesion problems. I did however paint my "Bronco" fender emblems last year and so far they are holding up. I sanded them with 180 and used Variprime which is Dupont's etching primer followed by 2K primer. Sanded that with 400 and a scuff pad. Sealed and painted black base/clear. Sanding with the 180 will give it a good mechanical bond and the etching will help ensure the bond. If your chrome is in bad shape, what do you have to loose?

i have sprayed a fair amount of chrome parts. i use basf products. they have a primer/sealer called poly-uroxy that is AWESOME for this. durable as heck! it has the speed of a polyurethane and the bond/durabilty of an epoxy. best of both worlds! i use it as a wet on wet sealer and have never had an issue with it coming off. very chemical resistant as well. i just scuff the chrome with a red scotch-brite. i've used vari-prime in the past but i don't think it is near as durable from rock chiprs etc...

On another vehicle, I stripped the chrome, scuffed the stainless primed and pained it an eggshell black. This was just body line molding. I had Aluminum pieces anodized black. The primed, eggshell black rattle can looked better and lasted longer than the anodized black and was much easier to touch up.

not that it matters but isnt the molding stainless. would still need to scuff it.

polyuroxy will stick to ANY metal and even glass! painted 1/4 windows on a new mustang back in '05. customer didn't want any louvers or anything, just a smooth panel. aftermarket smooth panels were 300 a pair at the time so the guy said let's give it a whirl. still looks good today! it's an impressive product!

The trim I am talking about is the aluminum side trim. I was thinking to use an etching primer, then prime with zinc chromate, then base/clear. I was just wondering if anyone has attempted this and what were the results or pictures. I have done a conciderable amount of painting with akrylic, never base /clear

If it is aluminum and in good shape without any deep scratches or gouges you could sand it with 320 and follow that with a red scotchbrite pad. Then wash it with prep solvent and dry it, spray the etching and let that flash. Then just spray 2K sealer and let that flash off. Then apply the base/clear. Doing it that way is faster and easier because there is only one sanding step and you will get the same end result.

Whatever etch, sealer, or paint you use check the TDS sheet. The TDS (technical data sheet) will tell you the substrates, mix ratios, dry times, everything you need to know about the product. To find the TDS just type a search in Google like "Spies 5400 TDS" and that will get you Spies 5400 primer/sealer TDS.
