I am currently restoring eight bikes that were damaged by a house fire a few years ago. I have been lucky in finding decals and the detergent and water system seems to work for me when applying the decals. My go to for some decals has been a lacquer overspray clear coat. But with the Velocals decals they recommend a lesser paint, so I have used an enamel clear for the latest set. I would recommend that very light coats multiple times to get the best results. The current Paramount project will take up to three days to get the clear coat right. In the past I have rushed the process and wound up with horrible results. Go slow and take your time is the best advice I can give for this process. Smiles, MH
