What techniques do you guys use to cut perforated vinyl without it messing up on edges?

So this question is mostly for car windows that have a rubber edge trim around the windows, where you cant easily glide the blade along it, how do you guys cut perforated vinyl without cutting the rubber?

You should cut back from the rubber approx. 1/8" and edge seal the perf with 8519 or edge sealer.

I tend to just use my finger(s) between the knife and frame as a spacer. Might not be the safest, but I find it easier to adjust for width and faster than reaching for another tool.

This is what I do. Just brace your fingers on the edge of the window wherever you can, and cut carefully. Takes a bit of practice. Try one of those mini snap-blade knives—I find them much easier to hold steady and cut straight than an X-acto, which just wobbles all over the place.

It also pays to use stainless blades so you don't scratch the window. If your a bit heavy handed a standard blade will scratch where you cut on the glass.
