This is a 100% bogus information! I have been using Acetone on gelcoat, as a wipe down / prep agent for over 30 years and have never once seen my gelcoat turn to mush.
If you pour it on the surface, and let it just sit there, it will eventually do some damage but why the heck would you do that? It will do no damage wiping the surface with a rag doused in Acetone. MEK is a another good wipe down agent that evaporates a little slower. I don't like oil based solvents such as straight mineral spirits because they can leave an oily film..
If you're still concerned about Acetone you can pay big bucks for Interlux 202 Solvent Wash or Pettit Fiberglass Dewaxer.
202 is a mixture of a bunch of potent chemicals like MEK, Cumene or isopropylbenzene, Xylene, Naptha and Cyclohexanone which is a similar industrial solvent to Acetone...
