How long is it advised to let paint cure before adding Sealant? A client of mine just had his I believe to be pride and joy painted. Paint was done well, high quality, nice smooth paint. He wants me to do a sealant job to protect the new paint. How long do I need to let the paint cure before putting a DA to it? There is no scratches or anything. The paint really does look to be a good quality job. It has been sitting in the shop for about a week now. Thanks!
