A while back we had discussion about restoring interior of Cal 20's I mentioned that I mixed Bahama Tan marine paint with a hi solids (white) primer to get a semi gloss finish close to what the factory applied. The paint is made by Zehrung Brands, A division of Zinsser Co. Inc. 173 Belmont Drive, Somerset, NJ 08875. It Iis called Z-Prime Plus. High performance Interior and Exterior Primer-Sealer about $12 a quart. I buy it in San Rafael CA from Jackson's Hardware at Woodland and Du Boise st.
