If you do a bit of searching on the LR forums you'll find some very (litigious) interesting comments about B&A as well. . . I think it must be the fumes from the Waxoyl
Again, I know a couple of people who have used B&A with varying results.
Maddisons did my old 110 Tomb Raider, they had it for a day and a half and made an excellent job of it. He cleaned it thoroughly, let it dry, waxoyld it and let it go off. Didn't charge me a fortune either.
