Painting on top of BMF

[Rat Fink]

I saw a post on here not too long ago by Mr. Obsessive and he put the BMF on the model before he painted. Is this correct and if so what type of paint or is any paint ok? I have a VW I'm working on and will want to do the chrome trim before I paint it because it's so small. Can someone outline the procedure for this?

I really don't know if I can help or not, but I'll try! Anytime I've ever heard of anyone using BMF before painting is if they are using for masking two tones or sort of like you said, protecting trim from getting lost, or masking small details. I would guess most paints shouldn't hurt it, since it is basicly very thin aluminum foil. I assume the trim you are trying to protect is the window frames, another solution would be using a scribing tool to better scribe the lines around the trim so it doesn't get lost under the paint, then put your BMF on the trim after painting. One other trick I've heard of with using BMF before painting is for small scripts and emblems, and that is putting the BMF on the script before painting, then after painting, CAREFULLY sanding the paint from the script to show the BMF underneath. I would use very fine polishing cloths for this, just enough to remove the paint but not damage the BMF underneath, and would do this before any clearcoat. I have never tried these before, all I have ever done is window trim and emblems after painting, but have read these tips in the magazines, so I hope they may help you.
