paint stripper and gelcoat

[Basketcase]

Am I correct in assuming that paint stripper won't touch gelcoat? I ask because I had a can and decided to see if it would take off the bottom paint which it did. It also took off a thin layer of white. I'm assuming this boat has been painted and I'm just taking off a layer of white paint underneath the bottom paint. Think I'm correct? Any reason not to use stripper? It works quite well on the spot I tried.
