Ken, Here's what I do. Take it from here. Dan.

Brush on a full strength coat of Valspar Lacquer Sanding Sealer NAS1420. One of those two-inch inexpensive disposable brushes is ideal for this application. Sand lightly with 220-grit sandpaper. Apply ¾ ounce fiberglass cloth over the surfaces brushing through it with the sealer thinned 100% with lacquer thinner. Sand lightly with 220-grit sandpaper. Brush on another thinned coat of the sealer. Try to fill the weave of the cloth as much as possible. Sand with 220-grit sandpaper. Brush on two more coats of the thinned sealer. Sand with 150-grit sandpaper to keep the surface flat and smooth.
Spray on three coats of Pacific Coast Lacquer’s PCL 913 lacquer based primer thinned 125%. Sand the first coat with 100 grit sandpaper, the second coat with 150-grit sandpaper and the last coat with 400-grit sandpaper. A Devilbiss touch up gun with a medium tip was used.
