Those pesky camshaft covers on the V12
Hej sån!
We all (well, most) have those black camshaft/valve covers on our engines. With age they start to flake off or just look tatty.
Before:
After:
Now:
I already did mine before but they are flaking again, as it seems the paint wasn't suitable for the job (no heat applied yet and they still just flake away).
So, what paint would you guys use? Doesn't matter if rattle/aerosol can or for the spray gun... I don't want to use POR15 on the covers, as the finish MUST be perfect (POR15 is ideal for things you don't see just incase there are some bubbles etc.) and that is basically only achieved using sprayed paints today...
Also, does anyone know what kind of "gloss level" the factory paint had? It wasn't high gloss, nor was it a silky type...
Cheers

They were of course "degreased" to make sure nothing would peal off again.
Powder coating would of course be a way BUT I don't need the inside coated and that wouldn't be a good idea... I'd have to seal the rear side to make sure nothing sticks there...

Surface preparation is the key to getting paint to stick. Sandblasting is good as it provides a slightly textured surface.
The surface MUST BE CLEAN. Clean with wax and grease remover multiple times until the rags are clean, aluminium is difficult to clean.
Once clean use etch primer to improve the bond, follow the instructions for the paint you are using.
Then prime and paint. It is important to follow the instructions on the tin regarding flash time and re-coat time.
I use green scotchbrite to lightly scuff the surface if I leave the paint longer than required time between coats. Like if I re-coat the next day.

heres mine 22years and counting. covers and manifolds.
glass bead blast to bare metal(not sand always dirty), glass ***** closes the pores!
good old fashioned marine grade oil base rustoleum paint(no primer), sprayed on let dry for many days , before putting on engine !
seems to be satisfactory , for the time, have been off couple times for minor work!
i have washed engine couple times, but no harsh detergents, just mild car wash soap!
exhaust mani's ceramic coated still look good!
again its your car do what you like
i have painted all my engines RED since 1949, no sense in changing now!, Red Hot and fast!! LOL
