Prep work is
part of any resurfacing job. Most finishes require sandind to bare wood if changing a product. Such as using "Armada" on a surface that had been varnished with another product. Most products, once initially applied, do not need to be stripped to touch up with the same product. Usually light sanding and a wipe with acetone.It isn't the most enjoyable job but putting TLC into your boat will bring your souls closer together.-DougS/V Brenda Gail
