Can I Use a Gel Stain Over an Oil Stain?
Gel stains are easy to control, and unlike penetrating wood stains, they can be used on non-wood surfaces such as fiberglass and metal. Applying a gel stain over an oil stain is no problem, as long as the oil stain has dried. Most gel stains are oil-based, so they are very compatible with oil-based stains and can be finished with most types of varnishes for good looks and durability.
