Other than making custom paint masks, what is the best way to mask curves with radius between 2-5 inches? Is there a way to use standard trim tape to mask to acomplish this without the tape crinkling and risking overspray?

I use the blue 3M Fine Line tape 1/8" and it lays down very good. The narrower the tape the better it will flatten out on a curve. Just do your outline masking with the Fine Line tape then use regular masking tape from there. I let the regular masking tape lap over the Fine Line tape then trim it on top of it with a razor blade, careful to cut only through the top layer. You can get the 3M tape at any auto paint store. Hope this helps.

I use electrical tape for masking curves- excellent and very pliable. Narrow vinyl tape like this can be drawn into very tight radii probably down to 1/2 or better. Warming the tape with a heat gun (carefully) might make it work even better but I've not tried. To be honest I am no expert at masking/painting but for the reltatively simple work I've done- its good.

Never, ever, ever, ever give up.

Thanks. I am using blue 1/8" 3M plastic tape, not sure if it's the same material others are working with for trim masking. Despite the 1/8" width, it's difficult to lay it down with curves. I wonder if Helimatt's suggestion about heating it up does the trick, since it's pretty cold in the NorthWest.

I'll continue to play around with this and see if I can get a satisfactory mask while painting panel lines EC135, which contain many curves.

Another way is to use wide tape and cut the radius with an xacto knife. You can make any kind of radius with this you want.
