Always nice to see a Johnson repainted Mercury Phantom Black!!

If black is the color of choice, for not much money I have discovered that Mercury's own and Quicksilver branded 3 part paint system in spray cans is really excellent, and holds up for years if directions on the cans are followed closely.

1st is the etching gray primer specifically for marine aluminum, mandatory for bonding to aluminum, number of coats as necessary. This is the key to long life of a paint job. Then, after some sanding, within an hour, two coats of black paint must be applied, The third application is the clear coat, which also must go on within an hour or less of the black paint. Evidently, all three cure and bond to each other. Once you start the primer, you go all the way to the clear coat in a total of about two hours, with two coats of each phase.

After curing for a couple of days, you can then wet sand with #1500 or #2000, and buff with 3M Finess-it II followed by a clear coat scratch remover (I use KIT). The result is a factory looking paint job specifically for the marine environment.
