Hi all, I've been having a look on the site at the various kits etc but before I get any further I have a quick question.  I'm thinking of making a petrol tank for my bike - what would I need to do for this?  I'm assuming I'll need some sort of iner tank or can fuel mix with carbon safely?  Has anyone else gone this route before?

Thanks in advance!

I use a phenol novolac sealer which is from a UK based company and is apparently a higher Phenol Novolac content than most which have been blended to reduce some of the costs. I am not sure how much there is in Caswell tank sealer but it is more expensive than I pay as I go straight to the supplier who makes blended resins.  The trouble with pour and slosh coating is both wastage and possibly having the sealer slump and not fully coat the inside. I paint mine onto the inner sections before I bond them together and I use an adhesive I make which is based on the same resin. This allows me to alter the resin with thickeners and additives to make the adhesive or sealer work how I want. It is not a cheap resin to buy but I would say I can do 3 fuel tanks with 1.25Kg (resin and catalyst total weight). So it is not too bad when you look at it per tank. If you are doing them to sell then obviously you would be buying 5 or 10Kg so would get a better price too.
