i used this in my fiberglass tank very easy to use

a word of warning about flexible sealant liners - if you use one of these liners then suffer structural damage to the tank, the liner makes it much harder to repair the tank (fibreglass, steel or aluminium tanks). In the case of metal tanks, you can't use any process that involves heating for the repair. In the case of damaged fibreglass, the repair will be complicated by having the internal flexible coating.

For fibreglass tanks like yours I recommend lining with either petrol-resistant polyester resin, or with epoxy resin. They are available in a viscosity grade suitable for lining our tanks using gravity to spread a thin layer over the internal surface. I've successfully lined many 1960s and 1970s Spanish fuel tanks with epoxy. I originally started lining them because the fibreglass was in poor condition internally and I was worried about possible petrol leakage damaging the paint scheme I was about to apply. That was quite a while ago now. The new components in our petrol are now another good reason for lining them with epoxy.

I use this stuff bought from our local boat shop http://www.westsystem.com/ss/

If you search some of the TC forums I think you will find that Caswell's tank sealer and Red Kote are most often mentioned and recommended. I've personally used Caswell's on at least 6 tanks, with excellent results.

See www.caswellplating.com and www.damonq.com for additional information.

West Systems is the epoxy to use. Modern fuels contain ethanol which soften polyester resins (the common resin for fiberglass).

thanks all will look into these, had my garage broke into week before xmas had my crossers nicked so its back to restoring the monty`s want to finish them and prob sell

Caswell...look no furthur!
