Re: Pettit hydrocoat eco paint
Just had my first experience using petit hydrocoat. I have some experience with other bottom paints (WM-CPP which I use on my boat) and some interlux varieties - all oil based.
The old can of < 1/2 gallon I mixed with a drill paint stirrer for nearly a half hour. After using this old paint it appeared to drop small clumps of paint or paint chips on the surface just painted with a foam roller. The old paint was mixed in the can. So we opened a previously unopened can which was of the same vintage (over 1 year sitting and maybe endured some cold weather). I used a 5" long razor to delicately nick the chickenpox like marks on the hull off and re-covered most of those areas with new paint.
Again, I mixed the new can for nearly 1/2 hour and it still showed some lines of different shades of red. Probably the best thing to do with old cans of this stuff is to take to a place where they have a paint can shaker and have it shaken up, as the label recomends.
The newer paint left a much cleaner surface with the foam roller with few imperfections. It was a warm day (80f) and as the paint sat in the rolling pan it began to skin over which translated into some small globules in the paint job. If I smeared those globules with the sponge roller to smooth and stretch them out it left a slightly brighter red pigment which I tried to re-cover.
Overall impressions of this paint.
It is a bitch to mix up properly, but it does not smell as bad as the CPP or other interlux oil based coverings. I highly recommend getting this paint shaken up at a shop that has one of those shaking machines. The alternative is to pour the 1 gallon into say a 5 gallon bucket and mix the shiz out of it. Most bottom paints really need to be mixed up well to be effective (dont ask me how I know this) but Hydrocoat REALLY needs to be mixed up well before use.
Liking the water clean up and low stink (VOC) though.
Fast drying on a hot day (80f). Low smell (VOC). Cleans up with water! This is perhaps the best thing about this paint besides the fact that it seems to cover a lot of area if spread out nicely and not too thick.
