thanks Anthony, my only advice i can give you is have a fresh supply of BMF, I use the original stuff not the new improve chrome I find it very difficult to conform to the body. the most important thing is to have a brand new blade. In a way I find it easier when the trim is large it is easier to handle. If you can practice on discarded body it sure would help. Even after all those years, I still have the jitters every time I have to do it but once I start , I ease up and then it just gets easier as I get " in the groove". Hope this helps and good luck with your BMF future project.
cheers
