    If you are going to do a color change on a car how do they paint the underside of the trunk lid? The frame and sheet metal have zoids, crazy bends. Do you just prime the hell out of it and paint it?

    I sanded the daylights out of it, washed it with varsol, then primed the daylights out of it. Two coats of primer with a light sanding after, wash again with varsol and then paint. It was a lot of work, but totally worth it. We did the underside of the hood as well the same way.

    Varsol is simply a brand of paint thinner. It removes all oils and debris from the vehicle before moving on to the next step. There are other kinds, but Varsol is popular in Canada.

    Sand with 320 grit dry paper with your hands,..or if the paint is in really nice condition just use a red scotch brite pad followed by adhesion promoter then either a good 2k sealer or thinned epoxy primer,..then go wet to wet with paint,...there is no need to "prime" it,..yiur more than like asking for problems by doing so

    Use rubbing alchohol or a dedicated pre paint wipe never thinner on a sanded/ painted surface you intend to topcoat

    If your going with a similar color or one that cover the existing color easily,..just go directly on top of the adhesion promoter. Building film thickness in jambs with excessive unnecessary material is a bad idea,..will lead to lifting and loss of definition
