Hi

I'm in the process of stripping a wing area (open structure) of the elderly tissue and dope covering with a view to replacing this with Oracover.

Will this modern film adhere successfully to previously doped balsa surfaces?

I have lightly sanded the structure but it is impractical to remove every trace of the old covering.

Advice will be welcome please?

Thanks

Stay well

SW

Or polyester silk and dope with tissue on top, very light, very strong and looks wonderful (imo).

What model is it and what type is it? RC glider, FF sport etc.

I believe Oracover do a lightweight film that may be better if its a small lightweight model.

Re adhering to the previously doped wood - If it was doped long ago you should be OK as all the solvents will have gone from the dope, I would still use as low a heat as you can get away with and get the film on as tight as possible before final shrinking.
