There are several diffrent brands, Home Depot sells one in gallon cans that many recommended but I dont have the name in front of me, I will get it if you need it.
It is a stripper with a thick consistency that you spread on and let sit for a few minutes and then use like a plastic or metal putty type knife of varying sizes and shapes to scrape off the paint which it softens.
If you have multiple heavy coats of bottom paint it can take some time becuase of re-applications to get thru it. It works real well on one or two thinner properly applied coats.
afterward you use a cleanser to clean off everything and lightly sand and fair any bad divits etc. if needed and paint your epoxy paint of choice.
