Ok, I have about a billion barnacle pads to remove from the bottom of my boat. I understand that the pads are comprised of barnacle glue attached to the boat and on top of that a disk of calcium carbonate from the shell of the critter. <br /><br />My plan is to chemically deteriorate the calcium carbonate with muriatic acid or Snobowl toilet cleaner and scrape with plastic paint scrapers. Both chems are reported to do a great job from my web research. Also, gelcoat is SUPPOSED to be impervious to the effects of both of those two cleaners.<br /><br />After the chemical/scrape work I plan to use wet/dry paper 400, 600, 1000 and then buff/polish with a white cream like Dupont's 7 or something similar.<br /><br />Am I on the right track? Any suggestions?<br /><br />Has anyone ACTUALLY had a bad experience with muriatic acid or Snobowl on gelcoat?
