Anyone use decal strips for canopies instead of painting?

I havn't,
But I have had some success with liquid mask and rolling papers from a headshop :), actually the ciggarette shop.
You heard me, I cut the adhesive strip from the rolling paper and lay it along the edges then cover the rest in liquid mask.
the paper pulls the liquid mask to the edge of the paper and seals it for painting.
the adhesive is weak enough to pull the paper off when you remove the mask and leave nothing behind.

Altho the last time I bought papers there was a cop in the store that looked at me funny...when I told him what I used them for he had to come over and see my work.
He seemed happy I'd found a legal, healthy way of using the product.

I occasionally do this on subjects which have really complex canopies, such as German WW2 bombers. The trick is to spray the relevant colours onto clear decal, and then to cut the decal into thin strips with a new scalpel blade. Apply the strips in one direction first, and then, when they have set and snuggled down, and dried fully, apply the strips in the other direction. Use lots of set & sol to ensure they sunggle down properly, and take your time. When you have applied all the decal strips, seal them in with Future, and then, if needed, carefully apply matt varnish where required.

I use Gunze's maskol.
I first cover all over canopy and then cut the lines with a new blade.
