    I purchased this body online. It has 1 thin layer of white (primer?) and 1 thin layer of amber nitro. Plus a few dings and dents. I want to spray is a solid color (Oly) and then relic it ever so slightly. Do you reckon I strip to bare wood and then do all the painting steps or is that overkill and do I only have to fill and sand it?
    Thanks! 8BE83AB7-37CE-41DF-8E9B-BBF0669D3650.jpeg

    I'd lightly sand away any loose material, very fine paper of course, then seal the result. The previous owner has exposed raw wood and that's gonna need to be sealed and more, if this is ash, you may have to grain fill the exposed areas.

    Use a block when you sand! You'll be glad you did.

    If your solid color is acetone based, then I'd sand back the amber nitro. Otherwise the Oly will melt into the nitro and who knows what that might turn into.

    Fill any dings and block sand smooth to 220. You need to shoot several thin coats of shellac over the existing nitro because the color will migrate up into the white nitro if you don't. Scuff sand the shellac with gray Scotchbrite to create some 'tooth' for the nitro to grip. Shellac is a fantastic wood sealer and primer; it dries in 30 minutes and nitro sticks to it extremely well.

    Nope. All the prep work has been done for you!

    You mean by the previous owner? I’m sure he hasn’t. No grain filling, no sanding, no nothing. He just sprayed 1 layer of primer (not even bothered to cover everything) and 1 almost absentmindedly apllied coat of amber nitro. Not the best of preperation. Or do you mean the work has been done by the shellac?

    You don't need to strip or sand the existing finish off. Scuff the existing finish with 220 grit and spray a sealer. I too like Shellac as recommended above, but you could use a vinyl sealer if you have it before spraying lacquer. If you want to fill the grain, then now is the time. Grain fill, then level sand through the grits up to 220 or 320 and then seal then spray lacquer.

    If the surface has been sanded flat, and has one or two coats of stuff on it, use that as your starting point. What I meant was you don't have to start with bare wood.
