Painting the Hull

You should use Imron (Dupont's polyurethane enamel) or its equivalent.

I repainted my 66 mustang about 12 years ago (it's in the diaires). I didn't use Imron, but it has held up very well. I painted the hull, let it dry for three days, wet sanded, drew my stripes and wording, masked it off and painted the blue and red. Then I let it dry for two days and clear coated everything. I put plenty of hardener in the clear to give it a tough finish. I made sure all the solvent had escaped before overlapping by letting it really dry. Trapped solvent will pop off the clear. I used 3m's masking tape called the edge, it gives excellent hard edge lines. If you ever used vinyl treatment on the interior, be sure to degrease (prep wash)where people might have stepped on the fiberglass or you'll get fish eyes.

I had to look at the cans, the colors are acylic enamel and the clear is urethane with a hardener or activater or whatever you want to call it. I don't paint cars, only 1 boat. As far as measurements, a body shop told me to put a little extra hardener in but not way too much or it will not cure. The paint I used is not made any more and the Imron is more popular. My sorry choice of words,"plenty" should have been written as precise, exact measurement, don't be short,don't cheat yourself.

Awlgrip is a brand name (similiar to Dupont). I believe Awlgrip makes a urethane paint similiar to Imron (product name), but I am not certain of its name. Awlgrip specializes in marine finish systems of many types.
