Re: can u fiberglass in cold?????
You would need to bring the substrate up to temp first..
Basically if your boat is ice cold and you have a hot batch of resin/glass ready. It will not work too good ( even if you heat gun the repair tops ).
Heat lamp or heat gun the substrate then do repairs..then heat the repair after application.
WARNING !!
If you try to apply a Thermoplasic resin in Inclimate temps you Really should know about substrate and top reps...
Dont try in freezing conditions ... both surfaces should be at the same at least close temps..
Working in a perfect world of coarce
