just thought i would share my experience using fiberglass on the inside of my van.
for anyone wanting to order some its £69.99 from fiberglassdirect.com comes with everything you need to do 5sm.
if you are doing it in low temps then use more hardener because it took 24 hours for one coat to dry due to the weather, also its a messy job so use rubber gloves and overalls .
the finish looks 100x better and should last forever with a little touch up here and there to make it look neat.
