Primer or not?
 

Ok this might be one of the most stupid questions posted but,
I am spraying over a faded 4 inch piece of Gelcoat. I dewaxed, sanded with 220 then 400, then 800. Faded green is all the same. I thougth I read on a forum you did not need to apply primer first?
Any comments.
Thanks

You re gelcoating? If so no you do not need to prime first.

Nope, Urethane Spelling :D

Follow your paint systems recommendations. 800 scratch in gel seems high. Depends on what paint your using. Also it depends on if your changing color.

I put on primer. Story over :drink:

For future reference, single stage doesn't necessarily need primer, but a sealer to play it safe, especially if painting yellow so you have uniform color. I usually sand with #320 before painting, but #400 if you use Awl Craft 2000.
