I did a small gelcoat fix using paste- added pigment. The first go around look good so I tried<br /> to expedite the curing by putting a heat gun to it.<br /> Area started to show an air bubble so I wiped it off with acetone and started again. Mixed approx. 1/2-3/4 teaspoon of paste with 1-2 drops of MKEP.<br />(these drops come out of the tube rather large so I don't how accuarte I am)<br />Masked area right around the gouge with plastic frisket film( the stuff used to cover textbooks for school) and cut the frisket with a blade <br />extremely close the repair. Applied the paste and covered with 1-1/2 inch cellophane tape in which I removed most of the adhesive by applying and removing from a cloth surface several times. This is trick that was told to me by a fellow boatsman.<br /> Anyhow, the job is now 24 hrs old and when I lifted a small portion of the tape it seams some of the gelcoat is still tacky as some comes up (very little) while the rest remains. How long should I really give to cure as I am always leary that I either put too much or too little hardener. What should my next course of action be. Will it inevitably cure with either over or under use of hardener. Thanks for your help.
