What clear coat and how to for polished aluminum

I just had about $800 worth of work done to my original aluminum side trim for my '64 cutlass.. It was recommended to clear coat it..

What clear coat do you guys recommend that won't yellow or haze..
Plus, i figure I have to prep the aluminum. I feel very queasy about etching the molding... How do I go about prepping the aluminum for the paint and clear coat.
Thank you for any help

I would see about getting it clear anodized. It should last indefinitely.

Now I know nothing about a 64 442 but if this is a restoration, I think someone has given you bad advice??

I say if it came from factory uncoated leave it uncoated.

Don't know, this is new advice to me.

I can see nothing but problems down the road if you do clear them.

There's a product from KBS called "Diamond Finish" clearcoat.
It's a moisture cured urethane (MCU) that should work well
on aluminum trim. It's very hard and non-yellowing.

I wouldn't etch polished aluminum, just clean it well before
coating.

If you decide to try it, DO A TEST PIECE FIRST.

I know I want to paint the center glossy black as well before clearing it...

The place the polished/cut&buffed and took out all the dings and dents recommended that I clear it...

So I probably wouldn't have to do any etching to paint the black and clear it??

I would also prefer not clearing it, i'm just going by the metal shops recommendation.

Have you looked at Zoopseal? Not reccommending it as I've never tried it but that's what it's for.

IMHO with out a good prep like alodine, the clear will only give you heartburn and look like crap down the road , Its why they invented "mothers" and elbow grease. If you want to do the center sections, clean well, use an etching primer like alodine and shoot a single stage.

If I remember right, when i painted helicopters, the Alodine changes the color of the metal. Gives it an orange tint. That wouldn't do him any good.

I recently made some polished Aluminum panels for my Car, and was looking for a solution to tarnishing also-I found this stuff-does anyone here have any experience with it? Looks like the real deal (and reasonable)-

Underground.. your absolutely right, Alodine will discolor the aluminium. Should only be used where you you want paint to stay put.

Personally, I have always liked and had aluminium parts rather than chrome.
The beauty of aluminium is that the more you polish it the shinier it gets.
I have used solvol autosol for 40 years now, and it still takes some beating.
I would never dream of coating aluminium with anything but elbow grease.

After reading some of your post and talking with a couple friends from a metal shop, I don't think I will be happy clearing or using anything to chemically etch then paint the molding..

It's not like I am going to leave my car out in the elements when I don't drive it. And I think a good coat of aluminum wax/polish once or twice a year should keep it a shiny as it is now..

Thank you guys for your input. If anyone else has recommendations, let me know..

i do tons of polishing,and i think i would just leave it alone and plan on doing some rubbing once in a while
if its all just been freshly polished the trick is to maintain it.
dont let it get away from you, and it will be easy to keep up with any good alum polish
