The bottom paint was falling off, and in general the bottom was in need of some attention.
There was a question of what was underneath 15 years of build up, and pretty clear indication that there was no barrier coat ever applied, although there was an area at the bow that showed some discolouration, leading one to think that maybe it was a repair of some sort, as the paint would not have been applied over dirt, or could it have been? After removal of the paint, it seems that there was something that discoloured the gelcoat and it was simply painted over.
While the boat is currently residing in fresh water, there was indication of some anomalies, and the hope that some of them were not actual blisters.
After getting enough IP2000E in two colours to apply no less than 4 coats, hopefully 5, and bulk packs of 60 and 80 grit paper, a nice new (cheap) disposable orbital sander, and a #100 cartridge filter mask, (among other essentials) the game was afoot.
I’ve said it before, and I’ll say it again; if I ever again get a bright idea to do something like this, please whack me mercilessly about the head with a hockey stick. I could have turned the boat over to a number of people who have soda blasting facilities that would have made short work of this, but nooooo, I had to do it myself.
Number 60 is a very aggressive grit to go after paint with. You need to be exceptionally careful about how much pressure you use, the opportunity exists to not only go through the paint, but the gelcoat as well. The use of 60 was followed as a finish sand with 80, and then when it’s all done, it’ll go to the warehouse for a hand sand. This paper wears fast, you only get about a square foot with either before it’s done, so I’m going though it rather fast.
It’s almost done, thanks in no small part to the 50-70 breeze on Sunday. Everything within 100 feet of the boat has a nice blue hue, it’s all over the truck, in the truck, Ronnie’s nice new generator is blue, and I could have finished Sunday, except that the little orbital sander finally puked from the buildup in the bearings.
There’s white gel under all that paint, evidence of critters having taken up residence, and the crack around the cover plate for the skeg is obviously older than at least one coat of paint, there is indication that it was simply painted over. The good news is that there isn’t any structural issue, it appears to be vibration caused, and a simple grind and fill exercise will resolve it. The critters that were there appear to have taken up residence before there was bottom paint applied, likely in the first year or so, when the boat was in much warmer climates.
