Regarding the use of floor/ furniture polish as a grp separator, you should make sure that it is unsiliconed wax, otherwise you might get in a mess. Silicone & Gel coat do not like each other & you end up with snail trails on the surface of your laminate. do not forget that silicone is a moisture displacer.

Yes, good point. IIRC, it was beeswax.. or something similar.

you can buy none silicon based waxes specially for GRP work at such places as Glasplies of Southport, and there is no danger at all in these.
Some waxes say they are none silicon based but carry chemicals which have the same detrimental effects as do silicons, and for the bit extra you pay it's worth not having all the hard work and materials being dumped for want of a few quid.
I bought a new 1kilo tin from them a few weeks back for £13.50.
The last one I bought in 1998 so it goes a long way. :-)) :-))

Just go to any glass manufacturer and buy your wax there ,i buy all my glass supplies local to me and the price is very cheap  :-).I get mine from a  company that manufactures glass roofs so just check your yellow pages and ring one up easy  :-)).

you are lucky there martin, as health and safety exec won't allow that sort of trading, other than from certified outlets.
I have tried many times to buy from such places as garage door manufacturers etc and they won't sell to the public, and can face a very hefty fine if found to be doing so.........don't tell anyone on open forum , you don't know who's reading......seriously. :-))
I know it happens, and I buy from such a place myself, but I keep it under my hat, as the fine for the trader helping you out can be astronomical in relation to the "crime".murderers get less. >>:-( >>:-(
