If it was me I'd either take it to a sand blaster, or leave it to the pro's if I wanted a show quality paint job.
Sorry that's all I could suggest.

When I did the Geekster, I had all the Tins Soda Blasted, Very Clean Finsh and Smoth, No damage to the Surface. The Panel Beater was over the moon with them. It made his job a breaze. A mate of mine dose it ,,, Neg 0417 351 939

He is in Geelong, But he can arange to get the parts from you. He is always over on your side of town

If you want a stripper that doesnt burn,stink,safe to use and is used on aircraft around the world try this web site www.sea2sky.co.nz and will take of the toughest of coatings

All sounds sorted Kiwidave, but the big question is;

What colour?

anyone in oz use walnut shell???? for blasting ? spose to be gentler on the sheet metal ,,,,just a thort
