Brake clean will work. A friend who works on household A/C and heatpumps mentioned a chemical they use.
You spray it on, let it soak, then house it off. It removes the fine layer of deteriorated aluminum to allow better heat transfer.  I don't have name for it as he never came through and gave me some! try a household A/C shop or supply place for it. I'd use a product made by "Star Brite" called Toon Brite if I could not find anything else. It cleans the grime off of pontoons on pontoon boats quite well. No scrubbing at all.

I'd use the above products, painting would be done with standard Radiator paint if at all.
I know you show your car, but and, I would investigate the possibility of replacing the condensor with the largest new condensor that would fit the space well. You'll get better cooling form some of the new designs made for R-134a. Tha being said, The stock will work fine in most cases. Paint is actually for looks only and slows heat transfer. So I'd only paint if it needs it to look good.

Seal the tubes super well. Send the wife or S.O to the movies, toss it in the dishwasher on pots and pans cycle with one of those electrosol type tables instead of regular dishwasher detergent! Thos etabs are amazing, they clean layers of curd out of stainless Thermos with zero effort and scrubbing! Should demousifiy the evap pretty well.
   There is also a chemical available from GM dealers they use. maybe get it to pretreat before final assembly too.
