I have used this FCS putty on two of my boards now, and both repairs have held up great. After you mix the putty to activate it, it takes about 30 minutes until it is fully set up and cured. Pretty easy to use and get a solid repair from. Once it cures, it takes a lot to sand it down flush, so be sure to not use too much extra material if not necessary. Downside is that the putty can be tough to get off your fingers after you kneed it for a while to activate. The color of the repair comes out a light grey, but sometimes with some light green flakes mixed in which can look a little odd. The UV curing resins like Phix Doctor come out looking better and are probably easier to work with, but you know that this will work for you 100% of the time rain or shine.
