I had some issues and wasn’t able to finish Undecided in time for spring fever. I did get the white gelcoat sprayed on but because of the two tone scheme, I had to wait until the white completely cured to mask and spray the port side yellow color. With a small weather window last Saturday morning, I got all the supplies out again, setup my mixing station, my cleaning station (ready in-case the gelcoat should kick early in the gun), and masked everything off. With mixing cups, stirrers, MEKP, and the duratec ready, I opened the pint of yellow gelcoat (supplied with the boat) and it was solid as a rock. Crap. The gelcoat comes from a west coast supplier and because it’s considered hazardous material, is practically impossible to ship expediently. So I sanded away the orange peel on the white side and called it a day.

I was having website problems and couldn’t post about the Duratec. It mixed in nicely and it certainly did give the gelcoat a good cure in open air. However, it went down exceptionally lumpy but I’m not certain it wasn’t a problem with my spray gun.

By the time I had sanded away the lumpy bumpies, it needed another coat as some of the repair was showing through. I’m going to purchase a new nozzle for my spray gun (larger diameter) and see if that won’t resolve this issue. In the past, I’ve sprayed gelcoat, thinned about 10%, with this same gun with MUCH better results – still with orange peel but much smaller and easier to deal with without have to remove so much material.

    How many gallons of chemicals would you need to re-gelcoat a 19′ Catamaran? Roughly?

    Tobin,

    Sorry it took me so long to reply. When I re gelcoated the bottom of the Team Seacats Inter20 catamaran, I used about 1/2 gallon of gelcoat. I was spraying the bottoms and then about 10 inches up the hull. When doing a friends I20 (white), it took over a gallon to do a similar area. If you are going to do an entire 18 foot boat, I would guess that one gallon should be enough.

    So 2 gallons would be a safe bet. I am planning on 2 coats. The top coat using a wax. Can you reccomend an enexpensive spray gun i should use?
