WD-40 effects on gelcoat & fiberglass?
Recently, accidentally discovered something. While lubricating something or other on my Beneteau 343, I sprayed some WD-40 (wasn't using it for lubrication, just squeezed the trigger in my tool bin) on my gelcoat.
This area of gelcoat had some nasty wax buildup that had discolored badly. In my part of Fort Lauderdale, we get a LOT of airplane, highway, and general soot pollution due to a powerplant incinerator nearby. I tend to follow MaineSails excellent guide on boat maintenance, but Collinite has a nasty habit of discoloring after 2-3 months. Strangely enough, the WD-40 accidental spray shot took the nasty wax and dirt right off!!!
Previously, when its time to strip the wax down, I rely on successive washes of Dawn soap, and even then, ultimately have to rely on some heavy solvents like Acetone, MEK, or Interlux 202 to get it to bare glass. I *HATE* those solvents as I know they are bad long term for the gelcoat. But, so far as I can tell, WD-40 is a lubricant more than a solvent.
Whats to prevent me from using this stuff to strip/clean the boat? Much cheaper than dedicated boat wax removers (such as 3M's aerosol).
Any issues with staining? Thoughts?
