I am planning to strip 10 year ould bottom paint off of a Whaler I just bought. The previous owner had started the job, and found that acetone, and 320 grit wet dry sandpaper worked well, followed by buff and wax. The areas he did look great, but I wonder if this is the best way, and if the acetone could harm the gelcoat.

Any guinance?

Interlux has a product they call 299 PINTOFF
It works without damaging the gel coat. Good luck, it's a miserable job

A dealer told me to try ez off oven cleaner. It works, but it is messy.

I just got done doing the same thing, I used Dolphinite’s paint stripper with less than great results. You may find something that works better but I doubt you can find one more expensive. We ended up taking the majority of the paint off with the stripper and sanding the rest, starting with 120 grit and moving down to 320. I wouldn’t recommend unless you are repainting, which I did with Dolphinite’s Go Fast bottom paint, which seems to be working great. I had other areas to fix and didn’t need a perfect finish. I think Zxylene is less aggressive with the gelcoat than Acetone. Whichever way you do it, expect it to be messy.

Hey funenj, I have a confession to make. I bought some oven cleaner (only $1.98) and tried it. I have to be honest I thought you were nuts, but it works. I rubbed it a bit with steel wool and low and behold the stuff actually works. Now if you can find me a product that will help the Red Sox win the world series I'll crown you prince.

Does ez off leave the gelcoat in good condition? I don't plan to repaint the bottom. I am trying to restore the original gelcoat. The boat was originaly used in New England, and left int eh water over summers. I intend to keep trailered, and have always liked the clean gelcoat look.

I tried your oven cleaner thing again today. It works but you have to work way too hard for the results. I'm going back to my Porter Cable. Thanks for the tip though.

Can someone describe the process for using the oven cleaner?

How much do you put on?
How long do you leave it on?
Do you need to neutralize it with baking soda afterwards?
Does it effect the gelcoat?
etc., etc., etc.
