Hi Guys,
I am refinishing a Mariner 40 Seaplane flying boat after about 200 plus flights. All plastic covering has been removed and all lightening holes have been filled with lightweight sheet balsa. The entire fuselage has been fiberglassed with 3/4ounce glass and 2 coats of water based Flecto Varathane Diamond Floor Finish. This is my first experience using Varathane and it's a great working product and so much easier, faster than using a 2 step epoxy resin coating.
After reading this discussion here's where I think I may have blown it. I did not seal the balsa with a sealer like Deft Laquer or other. I just brushed on Varathane through fiberglass, lightly sanded and brushed on a second coat of Varathane. Did I blow it? Can I do something to save it? Right now it sure seems as hard as nails.
Also, can I use latex paint, like Krylon Latex spray as my final, FUELPROOF paint finish.
Please advise. Thanks!
