Re: 1960's 13' MFG carefree Rebuild (complete noob, i know nothing about this!)
Yes, that is exactly what I am saying...I actually have laid CSM directly over still moist/soft fillets and used the CSM to actually give the fillets shape...If you continue to add layers of resin/glass over it, the chemical reaction created by the successive layers will begin to create so much exothermic{?} heat that even if you kick the resin slowly, it will be hard by the next day, at the latest...if your temps remain above the minimum required...
Like a lot of things that cure chemically, it can take as little as a few hours to several days, or even weeks...but it has been my experience that once the resin is hard after about 24 hours, you can do with it what you like, paint it, gel coat, use it as is, use it as intended without any adverse effects...if you want to fully cure it, you can put an additive in the last layer of whatever your topcoat is, whether it be resin/glass or gel coat...the only concern I have had with having resin fully cured is when I need to add more layers on top...sometimes as little as a week has gone by, and I would need to sand the resin to be sure to get a good mechanical bite, other times it has gone for longer, and all I have had to do is wipe it down with Acetone and go to town...Acetone is my indicator of whether or not the resin is fully cured...if I wipe it on the surface and it becomes sticky/tacky, I can lay more on top...if it doesn't I have to sand...
That is the way it has always worked for me...others may have different opinions or results...
Hope this helps...
