The weave is so fine on this nylon that 3-4 coats of Poly c might do it. I’m surprised how well it’s going in using light applications. The paint scheme will be 2k matt white and grey on top ( WW11 Coastal Command ) ** just checked this morning, one more coat should do it. I do know , the longer it’s left to dry the harder it gets. The test piece was done on the 23 September, 2 weeks ago, and it’s completely dried/ cured.

Starboard wing and where the nylon was purchased

About 2 weeks since I last posted about covering the wings. I’ve checked the test piece, and it really does stick hard! So now onto doing it for real 😬 Starboard wing has had its sanding sealer coat. I splashed out and bought a brand new 2” brush. The lightweight nylon is like gossamer, but will yield to curves etc. After putting a few pins in I went up the middle of the panel first with the glue then worked from one end to the other. Brushing in a light coat of glue and working out any creases.. Ive attached the invoice in case anyone else would like the same nylon. I’ll leave it to fully dry for several hours ( it’s raining at the moment), then go and have a look, I’m locking the garage door to avoid temptation

Not my house, but oh my what a noise 😁

Checked the test pieces this morning. The PolyC really does stick ! Test piece 1 is the smoothest and has the least warping, so I’ll go with that. I'm still concerned about the edges lifting. I think I’ll coat the edges and overlaps with dope and seal them that way. Test piece 1…

Cheers Martin 👌 I’ve done 3 different test pieces. homemade sealer then nylon cover/Ployc PolyC as sealer then nylon cover… etc Straight PloyC and nylon cover Each piece has then 5/7 light coats of PloyC. I’ll leave it overnight to fully cure. So far, I like the ease of clean down and no smell. It takes longer to cure and fix than dope. Maybe it’s due to the weather today, damp and rainy.

I will also try a couple of other methods. Use PloyC exactly as instructed, putting the cloth and PloyC straight onto raw balsa. And using Polyc as a sealer first then covering with nylon.

Set up the ailerons and tightened the push rods. I thought I might try and make my own sanding sealer and experiment with covering. This was PloyC and raw nylon. The sanding sealer was 50/50 non shrinking dope and talc, mixed to a thin cream consistency. I gave it 2 coats leaving plenty of time to dry between. I did find that if I was over zealous with the application the talc tended to clump as the dope flashed off. Once completely dried, gave it a good sanding with medium grit. To my surprise ( I didn’t know if would even work) the finish is like glass! Next was to get the nylon and attach with the PolyC. An even coat was applied over the entire length. Now left to dry. I’ll add some more coats this afternoon

Working on it😝

Noooooo🤔

I had a Flair kit, fitted with an SC30fs. I had to raise the trailing edge wing seat by at least 1/8” to stop it taking off nearly vertical 🙄
