My 71 Buick has clear that is delaminating in spots on the hood. I want to start to address this issue. My question is, If I feather the bad areas back, scuff the rest of the hood, seal it, paint it, and use a quality clear, will the clear that has been painted over be ok and not give me future issues? Or is it strip the entire hood of the clear and then start from there? Thanks.
It will likely continue to delaminate under the new paint. I wouldn't shoot over peeling paint, even if I sanded it smooth. Something was not done correct when the clear was sprayed. If it is just the clear that is peeling, you might be able sand off the clear without removing the basecoat and then re-shoot clear. If you have the matching base coat already, I would get the clear off as much as possible before repainting.
Delamination is more often than not the result of using products that aren't formulated to work together and or cheap clear. Or less likely the flash time was exceeded and the chemical adhesion is lost. I agree if its turning loose in areas the rest is to follow and going on top of it is not ideal. For a carlot repair sure,..it will certainly make matching it up to the fenders easier. To repair it correctly you will need to get the clear off via DA,water paper, etc,..then seal or 2 coats of primer surfacer if there are a lot of burn thru's. Then prep the fenders for paint and blend over the top of them. I do not reccomend using different brands of base and clear. It will only cause issues
If it's just been sitting in the sun,..no product will stand up to that,...now we have a care/upkeep issue not so much an adhesion issue
