I hate bottom paint....

[BigNiner19]

Spent all day trying to remove the old bottom paint from my boat. Most of it has already chipped off...but there is still some there that needs to be removed before I paint my boat. I got down underneath with a sander and some heavy grit sandpaper, and also used a putty knife to chip some way. I was able to chip more away than I could sand away. I headed to west marine to find something that may assist, and found the peel away pro. I just brushed some on to test it out. I'm gonna let it dry for a few hours and then see how it works. I hope it works well...I dont want to spend a week taking bottom paint off.

I would think this peel away stuff would work given the condition of my bottom paint. Like I said earlier, most of it has already peeled/chipped/worn away. But there is still some especially towards the front of the boat. Boat isn't huge either (15.7 ft), so hopefully this peel away pro stuff from west marine works.


Anyone suggest some better "bottom paint" removal tactics or solutions?

A 3000 PSI pressure washer will get most of it if it is flaking already. Rent one for a day.

Cory, I think you are on the correct path. The pressure washer may or my not get the paint off. Watch to see it doesn't strip off the gel coat.

I used the pressure washer, fiberglass paint remover, putty knives and even my heat gun to get the bottom paint off. The paint remover works really well on a single or small number of coats of bottom paint. In places where it had built up, it doesn't work as well. I eventually endeed up sanding the entire hull, and then priming it with epoxy barrier paint to prevent water absorbtion.

You look to be right on the money. I put on some of the paint stripper stuff and it bubbled up the bottom pait where it was already pretty weak and allowed me to take a putty knife and chip it right off. But in areas where the bottom paint is more in tact, it hasn't done much at all. This is going to take me forever.

You may want to look into getting it soda blasted. It's not that expensive and does a really good job
