Cover then add the canopy last. You might want to try someting I just did on a 4 * 60. Painted the inside of the canopy black then used matching Ultrakote strips to trim out the canopy frame. After the frame was trimmed out, I used thin black trim tape to mark the canopy seam. Be careful when you cover a canopy with covering. Use just enough heat to activate the adhesive, you don't want to melt the plastic. Little bit of care and you will be pleased with the result. Hope this helps. BTW read this tip a long time ago on the old RC online.
