Here are some experiences we had with the SC1000 coating on our past boat. below text taken from thread linked at bottom
Two coats down and one to go. I have one gallon and it will be enough for three heavy coats on the side walls of the v-berth and the end wall where the anchor locker is located. That will give use plenty of untreated overhead panels to compare performance. The product is basic white and the thickest paint I have ever dealt with. I popped it open to stir it and realized there wasn't much point. It is some thick that it can really settle out. I would say it is like a Wendy's frosty that never melts if you are familiar with that treat. It does not drip at all and is very easy to apply with a brush. I am using a half inch for trim and a 2 1/2 inch for the walls and it goes fast and easy with each coat taking about 20 minutes. If it turns out to help significantly with condensation/noise, I will be buying another gallon for sure and do the rest of the v-berth not already covered with foam padding. We have grown quite fond of that foam.

It dries flat white with a brushed texture and looks quite good. You could always have any paint store tint it for you for another color. I do not plan on any topcoat at all and I think a gallon would likely do at least a couple of coats in your boat. I plan to test it out overnight this weekend and will post my results. Third and last coat goes on tonight!
Well, I got three heavy coats brushed on the sidewalls and anchor locker wall and did not quite finish up the gallon. I spent two nights in the boat during the last few days and the results are promising. I would say the most noticable difference is less noise with thermal insulation coming in second. It is noticably quieter up there but I wouldn't call it warmer. I wish I had one of those thermometer guns to verify but I can feel the difference in temp between the coated wall and uncoated wall with the back of my hand. Don't get me wrong, they are both still cold but the coating makes is slightly less so. The condensation is severely reduced but I would not say it's eliminated. I slept all zipped up with the canvas cover and hatch closed to make it worst case scenario and generated the standard condensation issue we are all familiar with. The treated walls were dry except way forward and near the uncoated ceiling it was somewhere between clammy and slightly wet. The wall adjacent to me was wet where uncoated and dry where coated so it really does make a difference! I still feel the need for some soft thermal insulation from those walls down low where a sleeper comes in contact with them and I will use a simple long panel section of removable foam for that (pics tonight).
So the moral is, yes it does work primarily for sound and second for thermal insulation but is still a long way from warm a fuzzy. I will buy a second gallon and do the rest of the v-berth but not the sections I already have covered in 1/8 inch foam. The foam IS warm and fuzzy and we loved it immediately as head padding so it stays.
The product goes so far at least with brushing that I will also add another coat to the walls for good measure. Spraying may allow for a thicker build and better overall results but I will leave that to someone else with a masking fetish to try.
80 bucks per shipped gallon (2 total for multiple coats in the berth) is worth it in my opinion and I am wondering how I will resist coating more of the boat. If Cindie takes a real notice to the difference, she will want to do the whole boat. Cold is Cold so we will see if the quieting adds enough motivation.
Followup on the SC #1000 coating. We ran the boat out in some rough water (sustained waves over 7ft) and for some high speed cruising and the difference in sound was big. With the coating on the walls of the berth only, Cindie really noticed while underway and she also noticed increased quietness when going to sleep. This coating really is an acoustic barrier first and thermal insulation second. We had the boat out overnight with the three of us running only the wallace for heat with just one window cracked (usually have two) and had some condensation on the coated surface. It was less than before but still there. The new foam pads against the walls were fantastic. The sound deadening qualities have Cindie wanting to coat the lower half of the remaining interior so that project is on the list. It really makes a difference.
