<div dir="auto">The cause of the wrinkling is the thin gel coat. If you think the gel coat is marginal in terms of thickness you can better your chances of getting away with it by applying a "hot" brew of resin when laminating... If you leave the gel coat to cure too long you will still be able to laminate over it the only problem is the long term adhesion and the possibility that there may have been contamination to the cured surface, always better to strip and do again.... <div dir="auto"><br></div><div dir="auto">Mike. </div></div><br><div class="gmail_quote"><div dir="ltr">On Sun, 16 Dec 2018, 9:25 a.m. Brian Cox via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="font-family:Arial,sans-serif;font-size:10pt"><font style="font-family:Arial,sans-serif">Hi All,</font><div><font face="Arial, sans-serif"> Fun and games with my gel coat project ! Thought I was doing everything right but apparently not. After waxing my mold 4 times ( 4 layers) then I applied the PVA mold release with a spray gun, that went well, so far so good. Then time to spray the gel coat, that went well also, though I probably did not spray a thick enough layer, but my big boner of a mistake was letting the gel coat sit too long, apparently I was suppose to apply the resin and fiberglass layers while the gel coat is still tacky otherwise the gel coat material changes chemically over time and crystallizes . Anyway the result is a big gooey mess, luckily I was able to stop before getting too far along. Instead of the gel coat adhering to the fiberglass it started breaking down and melting into the resin and it got all crinkly. So now I'm going to to wait and let what I've done set up so I can pull it off and start all over again !</font></div><div><font face="Arial, sans-serif"><br></font></div><div><font face="Arial, sans-serif">Brian</font></div><div><font face="Arial, sans-serif"><br></font></div><div><font face="Arial, sans-serif"> </font></div></div>_______________________________________________<br>
