The plastic over my windscreen is wrinkled and there are small holes in it here and there. I'd like to replace it but I don't know how difficult that might be or if there is an easy source for replacement plastic. Has anyone tried this?
I've had good luck with automotive crash wrap, the stuff they use to cover damaged car windows. For $40 Amazon will sell you enough for a dozen RV canopies: https://a.co/d/btY5GOU
I've used this stuff with great success on both my LongEZ and RV canopy's. Mask the perimeter where you want the fiberglass skirt to terminate, then spray or brush 3 to 4 heavy coats of this directly to the plexiglass, inside and out. It will protect the plexiglass from minor bumps, scraps, paint overspray and epoxy drips, dust, etc. Leave on through the airframe painting phase then simply peal off with your fingers.
3-mil self-adhesive carpet protector. Works great, no residue. $40 for a 24” x 200’ roll. My A&P has big feet…I use it to prevent scuff marks next to the wing walk. IIRC, someone on Amazon sells the stuff in 50 foot rolls at half that price.
