You can see in the picture where some of it was not affected. I think since it was so thin in some areas that the resin upon curing shrank and drew the gel coat layer into the resin/fiberglass. I may have over catalyzed the my laminating resin as well. Plus the fact that in the bottom of the curved shell the resin was thicker and created more heat. The perfect storm of errors !</FONT></FONT><DIV><FONT face="Arial, sans-serif" size="2"><BR></FONT></DIV><DIV><FONT face="Arial, sans-serif" size="2">Brian</FONT></DIV><DIV><FONT face="Arial, sans-serif" size="2"><BR></FONT></DIV><DIV><FONT face="Arial, sans-serif" size="2"><BR></FONT><BR><SPAN style="font-family: Arial, sans-serif; font-size: 10pt;">--- personal_submersibles@psubs.org wrote:</SPAN><BR><BR><SPAN style="font-family: Arial, sans-serif; font-size: 10pt;">From: "MerlinSub@t-online.de via Personal_Submersibles" <personal_submersibles@psubs.org></SPAN><BR><SPAN style="font-family: Arial, sans-serif; font-size: 10pt;">To: Personal Submersibles General Discussion <personal_submersibles@psubs.org></SPAN><BR><SPAN style="font-family: Arial, sans-serif; font-size: 10pt;">Subject: Re: [PSUBS-MAILIST] gel coat nightmare</SPAN><BR><SPAN style="font-family: Arial, sans-serif; font-size: 10pt;">Date: Sun, 16 Dec 2018 21:46:59 +0100 (CET)</SPAN><BR><BR><P style="font-family: Arial, sans-serif; font-size: 10pt; margin: 0px;"><SPAN style="font-family:arial,helvetica,sans-serif;font-size:10pt;color:#000000;text-decoration:none"><A href="https://www.fibreglast.com/product/gel-coat-troubleshooting-guide/Learning_Center">https://www.fibreglast.com/product/gel-coat-troubleshooting-guide/Learning_Center</A></SPAN></P>

There are a lot of factors that affect the resin, humidity is a big one along with temperature. Definitely not as easy as making a surfboard ! Luckily I have a guy that is sort of guiding me through this, I ran into him in the boatyard and I've been calling him when I get in trouble, a very helpful guy, he says he can sympathize since he's already been through it. But he says even the pro's have issues sometimes when the elements throw you a curve ball. I thought by waiting until the next day it would be better since the shop would be warm during the day but I didn't realize the critical time frame on applying the resin after the gel coat.</SPAN></SPAN>

<DIV dir="ltr" style="font-family: Arial, sans-serif; font-size: 10pt;">I hate working with glass and am not looking forward to making my MBT's! if it's any consolation, I knew of a guy who was building his own 36' sailboat out of fiberglass in the late 60,s and he didn't get the resin/hardener ratio correct for the temperature and humidity for that day and it never set up all the way! Never did hear what he did but probably sold it as is where is and went out and bought one all ready done!

<DIV style="font-family: Arial,sans-serif; font-size: 10pt;"><SPAN style="font-family: Arial,sans-serif;">Hi All,</SPAN>
<DIV><SPAN style="font-family: 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 !</SPAN></DIV>
