Bottom Paint removal
 

I know this has been discussed many times, but I was wondering if anyone has tried any new products lately? What is the most painless procedure? It's a 25 foot boat & the owner is ready to go to work on this project. Any help & hints would be appreciated. Thanks,

download this. good info.

I just read an articale in powerboat & motoryacht regarding blasting bottom paint off of fiberglass using baking soda as the blast medium. Sounded interesting and effective to me.

Check out these products. I have never used them, but they say to just roll it on, let it sit for like 24 hours and then pressure wash it off the next day.

I used the back to nature stuff on my 40ft cruiser. It took six weekends, 24 gallons and five coats. The bottom is still not completely stripped. The hard part is anything near or above the waterline and around chines. I think the back to nature stuff is good for the gel but not strong enough to easily attack the paint.

I had about 5 coats of bottom paint on my 29 fourmla p.c I tried chemical stripper and scaping for 2 days befor I got out the sand blaster! I am refinishing with epoxy primer and imron as I keep the boat on a trailer now! The sand blaster is the quickist way but it does etch the gell coat! Just right for primer. But be carful, It is easy to eat the gell coat off if you get to close!

What did you use in the sandblaster as the medium?

I have just tried this method and found it works ever so slowly. I bought a cheep (home depot) Husky sand blaster. It worked OK for about 30 minuets and then it just did not seem to be pushing enough of the Blaster type baking soda. I took the nozzle apart and found that moisture in the air line had caused a caked up residue of baking soda in the area of the venture. I cleared the obstruction and drained a small amount of water out of the water trap @ my compressor. The thing worked for about 30 seconds and then clogged again. After repeated attempts to clean the gun I gave up. Any ideas ?

Rent a pressure washer with a sandblasting attachment. Took 550 pounds of sand and about three hours to do a 20 foot boat. Sand is cheap.
