You have no idea how freaked out I was, when I found out that I had waxed my bow with a wax containing solvents, which ruined the finish and gave the limbs some brown spots. My main concern was the fiberglass - I was afraid what the solvents could do.
I cleaned it off, sanded it and refinished it. As it was the first time I finished a bow, it looked sloppy. I was pretty angry. Sanded and finished a couple of times, and now it looks great. It still has some brownish spots, but that just acts as camo now. I'm a perfectionist too, but I've learned that in time you'll accept it as it is. After all, it still shoots!
