[quote=tominpa]Primer is a good lesson in learning to apply this stuff. Do not fear the thinner. My first coat started off too thick and was difficult to get even, but not a big deal with a sandable primer. I added some reducer and started getting better results, but still not what I hope for in the final finish coats. Thinned to the point that the paint tipped well, it does not fully cover darker fairing compounds. By the second coat it should look pretty uniform.
Do not get anywhere near this stuff with clothes you remotely care about. No mater how careful you are, you will contact the paint. I was working in an open, well-ventilated garage, and will pick up organic respirator cartridges before the second coat. Pretty intense fumes that smell like isoamyl acetate used for respirator test-fitting.
I found suspending the hulls from the ceiling and starting at the stern, gives me the best chance to keep a wet edge. I coated the transom and top, ten proceeded around the outside. As I reached the bow, I painted the entire bow section ahead of the bridle wire tang, including the top side. then came around the bow, and continued towards the stern on the inside. This maintained a wet-edge on the top and inside-bow section. Try not to over-think this. The original boat was glued together on the stern and under the non-slip top in a pretty crude manner. The final paint job is going to look a lot better than that old seam.
The bottom of the boat is not visible anyway, and compared to the project linked by dmgbear55, the catamaran is small. I did both hulls, and used 1.5 quarts of primer with 10-12% reducer to cover everything, including the rudders. I was hoping to get coverage of both hulls with 1-quart, but this was in-line with my original esitmates for the 5.7 at 200 feet per coat. So my 3-quarts of final should give me the 2-coats I need, and I will get 2-coats of primer with enough left over to triple coat the bottom of the hulls and rudders. I am also coating the topside access ports since they tend to yellow in the sun.[/quote]
