Canopy frames

I use Testors Parfilm M. If you cover the lines, you can easily (with minimal patience), cut out the frame with a sharp knife. Other than that, just stay tuned and you will have all the other way everyone else uses at your disposal shortly.

I use Bare Metal Foil.
It's the easiest way to get perfect results. It's super thin, so you miss no detail - it cuts easily and conforms to curves easily. Just burnish it down after you trim the frames so you get no bleed under from your paint.

I do them freehand while wearing a pair of magnifying glasses. If it gets sloppy,
I make a chisel out of clear sprue and clean it up. Works real well for me.
