3. In a tent erected around a hull, what sort of temperature is require to dry it out and how long will it take?
Use a tent by all means but allow a fresh air draught to do the job for you, the time taken will depend on the average relative humidity. Check progress with a moisture meter.
4. Which is the best solvent for removing grease from GRP?
Instead of using volatile solvents such as cellulose thinners, which are hazardous to both you and the environment, try a strong detergent solution such as our General Hull & Work Cleaner. It tends to 'kill' grease instead of thinning and spreading it as a thin film over the surface where it can act as a release agent. Contact us to purchase.
5. What's the best way to clean lay-up brushes of resin mix.
Use disposable brushes. The cost of solvent is usually more than the value of the brush. The corollary is you are being environmentally sensible!
6. I've some epoxy resin which is three years old. Is it safe to use?
Epoxies generally have a published storage life of 2 years but if you have a considerable amount it is worth mixing a sample in the correct proportions and leaving to cure for a day. If the system does cure to an infusible solid, then by all means go ahead.
