I just had the exterior of my 13' 1972 BW professionally painted with Emeron paint (3-coats) I did all the prep work beforehand. I'm a little dissapointed because there are literally thousands of tiny potholes (smaller then a pin head). Painter informed me that it is a common problem with painting fiberglass boats. Is there anything I should have done during the prep work or the painter could have done to prevent this? By the way, the painter is very experienced and is the head painter at the largest tractor trailer repair facility in the northeast, so I've got to believe what he says. Plus he only charged me $50.00 (helps to have connections).

I think you are talking about ImronŽ polyurethane enamel, a DuPont product.

JIMH - You're correct, that's the exact paint. Are you experienced with it. Can it be sanded and resprayed to hide the pinholes?

Your "painter" is full of it. Pin holes re usuaally due to water or oil being in the air lines of the paint gun. If the air lines from the compressor are not dry and plumbed well to keep dry, this is the result. It could be in the primer layer, or any layer of paint, you can always sand and repaint but don't use him.

BIGSHOT - Thanks for the input. You always seem to be looking out for us nimrods. I'm going to ask the painter if he thinks that was the case and evaluate his feedback. Regardless, I'm going to re-sand and paint again. Any suggestions on size of sand paper?

Nope but....add some "fish-eye" inhibitor to your paint, should help.

You failed to say if you primed the hull.If you only sanded the original gelcoat and did not prime, you opened thousands of pores in the gelcoat. You must prime to fill those pores or the finish will appear as you are describing. Could also be solvent "POP"., not enough flash time between coats.
