Re: Paint prep
Most of my model A's were covered in surface rust to start with . If it still has paint on it, the first thing that I do is wash the vehicle with soap and water . If the surface has had wax applied in the past, sanding doesn't completely remove the wax . Wax causes fish eyes in the new paint that will be applied . I then solvent wash after the soap and water wash . . Never wipe with a tack rag over a wet surface , especially a solvent wet surface . A tack rag is coated with a sticky substance that picks up whatever dust that remains on the mostly clean dry sanded surface , before spraying on the paint . Most if not all paint suppliers have a special solvent to use before applying the paint . It doesn't matter if the solvent is prep sol , final wash or whatever the brand calls it . I have often used enamel reducer as a final wash before applying the paint . Never use lacquer thinner as a final wash because it can loosen and smear the old finish and make a mess .
