I have a story to tell ya about bottom paint removal, trust me it ends great.
1st of all I had a customer who wanted me to remove the bottom paint from a Rinker 232 and bring back to original gel white. I really did not want this job as it really sucks to do. I have done it on other boats also. Now the good part. My wife wanted a boob job, ya a boob job. But they are incredibly expensive. I told her to get an estimate for double DD's. I said "whatever the estimate for the boobs will also be the estimate for the bottom paint removal, but you have to help" Any way the estimate came in at just around 5k. So, the bottom job was the same. I never would have guessed the boat owner did not even hesitate and said "Do it". So the boat owner got a clean bottom and I got a new pair of toys. lol. Double D style.
Now for how to remove.
I used Petits "Bio-blast" bottompaint remover. Basically brush on and let sit for a while and scrap off with an ice scraper, and other plastic putty knives. The bottom came out great. I then had to sand and respray the bottom with new white gel coat, buff to shine. My wife did help alot also. The job was close to 40 hrs in labor plus 2 qt gel coat. Good luck Al
