Wellll, I know I should be fishing but. I got tired of playing with my little chunk of test glass and went to slathering in the boat today.
Sound deadener or DeltaTdb - This stuff has about the same consistency and looks as aluminum roof sealer. For some reason I chickened out on trying to spray the stuff so I brushed on two thin layers in strategic locations. I did under the galley, back in the ice box hole and under the port, front seat. The stuff brushed on with no fuss or muss, it dried quick into a ugly black, hard surface. When/if I go for the total boat job I'll give spraying a try up in the rode locker.
Insulation - Once the db dried, I sprayed a coat of the insulation over the top. In spite of the manufactures info, this stuff doesn't brush on for beans, BUT, using a sandblasting gun with about a 3/16 orifice, the stuff sprays out in a real controllable, nice manner. The stuff comes out of the gun in about a two inch pattern with about no overspray, ya can really put the stuff where you want it. I had some second thoughts about spraying stuff around in the boat, but not now, if this stuff proves out I'm covering everything.
The boss stuck her nose in the boat when I was about done and wondered what was up, I told her to look under the sink....she didn't notice anything different..BINGO..that was was I was after, a quieter, warmer boat with no big visual impact. A person should paint or carpet over the insulation after it dries, I'm going to try some Krylon Plastic paint.
