Epoxy on aluminum radiator

I talked to Barry on the phone about this but my mind is a sieve for these painting details.
I recall he mentioned one good wet coat at 50/50.

What I don't remember is how to clean it prior to priming.
What grit should be used for scuffing the smooth surfaces?
How does a guy prep the fins?

Thanks for any help,
Pugsy
 
I know it will take a bit away.
At least maybe I could do the front of the condensor as that won't affect the motor's temp and do the edges of the rad that the condensor doesn't cover.

I just have to black out behind the grill openings.
I'm a little anal about this point.
 
a black screen behind the grille works good. keeps bugs out of the rad too . but yeah the shiny rad behind the grille is a little off.
 
Have it black anodized? We did that on a previous project where the owner didn't like the looks of the raw aluminum radiator.

This is an interesting idea as the annodizing is only a coupla thou thick.
 
It looks pretty good on an aluminum radiator, too. It's subtle, a nice touch IMO.
 
I called the annodizers today and was told ''about a hunert bucks'' but he has to see the parts first.

Translated it will come out about 250-300.

What happens to annodizing when exposed to 134a in the condensor? I can't see anything good coming from that.
 
anodizing is extremely corrosion resistant so i doubt it would even do anything to it. all the aluminum tubing we used to build the tuna towers with when i worked at the yacht co were all anodized so the alum would not corrode in the salt air and water. sportbike frames are all anodized alum as well and they are exposed to gas, oil, coolant, brake fluid etc.

Nothing, you have them plug the lines with some silicone plugs just like if you were having it powder coated.

I'd have to check with them. Like I said, they want to see it to confirm if it'll be OK.
Hopefully, it'll be OK.
