Field test results-
I wish I had some numbers to put to my findings but I don' but here it goes.
Cabin warmth- I have a pathetic little heater that previously almost took the edge off the cold, now, it seems that the little heater can keep up with the heat loss and make it comfortable. It's not shirt sleeve comfortable on a cold morning, but after setting out the fishing gear you welcome getting back in the cabin. In the evening we had a small electric heater with a thermostat, it would warm things up and shut down, it seemed to take a fair bit of time before the heater would kick back on again. Again, I wish I could put some numbers on this but..heat wise I think it was well worth the time and $.
Condensation- Usually we sleep with all the windows & the bow hatch cracked open and wake up in a rain forrest. Damp clothes, damp sleeping bag, moisture dripping off the roof...ya all know the sensation. Last year I installed a solar roof vent and it helped a smidgen (technical term) This weekend we had only one side window cracked open about 1/4 inch and we also had the electric heater going which we don't often do. In the morning there was condensation on the windows BUT the roof, clothes, sleeping bags where dry, we had none of the clammy rain forrest sensation..I didn't miss the joy of putting on clammy clothes in the morn.
I'm sold. The only beef I have with the stuff is a result of my doings, I sprayed it on a bit thin so I had a fair bit of material fall out (dust) If I had sprayed slower and applied a thicker coat I don't think it would be an issue. Twas easily resolved with a vacuum with a brush attachment. The boat looks nice in it's white coat and I'm tempted to leave it as is, but for ease of cleaning it's getting the Zolatone treatment
I hope this info will help make somebodies C-D experience more enjoyable
