used usc chemicals resin and hardener. skin coat on outside of rv nose still does not want to cure fully. sanding it only rips off the hard top skin and smears the soft under coat. put heat on it but that doesnt seem to be working. i have run the coach furnace also to keep both sides warm. i am in a headed shop also.

Probably old, bad hardener. ALWAYS do a test sample of fiberglass resin / hardener mix to be sure the MEK is good.

If polyester resin simply reduce the hardener amount. Your conditions are considered hot for working any thermo-set compound. If using epoxy resin the two parts must be mixed in the correct proportion, and the only way to get longer working time is by using a slow hardener, or working in a cooler location. Due to a high risk of condensation contaminating the mix, using a fridge to chill the resin before mixing is not recommended. The hardeners for polyester resin are completely different to the epoxy system, and a percentage of from 0.5 to 2% can be specified depending on the conditions and resin formulation. This hardener group does not store well becoming highly unstable (explosive) after extended storage in some conditions, at all times it is very bad news if you splash it in your eyes - blindness can and is the consequence, regardless of how quickly you get it washed out...

sounds like you didn't use enough catalyst, or you didn't mix it thoroughly, take it all off and start again. You probably wil have to get som Methyle Ethyl Ketone (MEK) to help you clean it off. This is great stuff, stinks to high heaven, but extremely effective in cleaning this type of mess up.

You didn't put enough catalyzer (hardener) in the mix, you have to start all over again, and don't skimp on the hardener this time.

not enough .emekay.
remove the resin,You already spur.
putty knife first, acetone the last residues.
before apply any fiber glass,test your skills some where else.likes piece of wood ,cardboard,etc.
