Hi Phil
Once you have found a paint supplier to supply the base colour coat, use the company detailed in the attached pdf for all your other needs, lacquer, primer masking tape, tack rags etc. Good quality products at a sensible price. The standard lacquer they provide is petrol resistant up to a point - OK for for everything apart from the petrol tank, but they do a more expensive lacquer which is petrol proof. This is shown on the invoice as PRO XL Pro Clear Lacquer at £8.99.
