Yes, lacquer. The stuff available in most auto parts stores. Durability and longevity is unknown but it will put my bike back on the road for this year. Being retired I really don't mind if I have to take the whole thing apart again next winter to have the frame done all proper. I got the time and I enjoy it. We'll see what life deals me.
Also, maybe, after a thousand miles or so I'll know the bike better and know how much I wanna spend on professional painting. Baby steps, ya see.
