Hi all
Thanks to all for you responses. You are correct about the silica additive just adding to the resin to thicken but after some pointing in the right direction I've actually found a polyester bonding paste specially formulated for the job in hand.And in 1kg tins @ £10. Can be used for bonding fibreglass to fibreglass or metal/wood to fibreglass and also can be used as a gap filler (perish the thought of gaps!!what on my car!!)
Any body interested look for crystic bonding paste 90-78pa.
cheers Ian
