After you have all the paint or as much as possible off of the boat then wash it off with the lacquer thinner. Apply the stripper from the top and let it run downhill. Use a cheap brush. I like the reference to “turtle” the boat. Keep it off off the floor, maybe on sawhorses. Thinner can be found where you get the stripper. Start out with a gallon of each and do the boat in stages, may be a third at a time. Whatever you do do,nt leave the stripper on for any amount of time where it will dry as you will double your work. You should be able to do this in a short afternoon if your set up properly. Like I said previously this is a nasty/messy job so keep kids,pets and your dearly beloved should you be so encumbered away from this toxic goo.
