Re: Need a bit of advice, noob alert, stripping paint from a thompson boat.
I will get shot for this.
You need chemicals. Methylene chloride based stripper and plenty of it. Apply the stripper, let it work about 20 minutes, go back and scrape gently. Apply another coat, to the first area, and scrape the second area, repeat procedure. Always keeping the area wet with stripper. After awhile, the finish is soft enough to remove with a nylon kitchen/dish brush.
I do canoes. I have tried heat gun and sanding. This is the only way to go. I did a 16 ft canoe the other day in 3 hours.
Use eye protection, respirator, cartridges, gauntlet gloves etc.
I do use a heat gun on trim and small areas.
My 2 cents.
