Crashed my Ultrafly SU27 into a bush and knocked a few chunks out of the
wing LE. Any ideas what the best filler would be (if any) for this
polystyrene foam wing?

Thanks for the replies guys.
I was in the local hardware shop yesterday and an assistant was restocking
the adhesives stand and by a strange coincidence she was hanging up packs of
"Evo-Stick Fast Foam" - cost £4.70. The pack (a double syringe blister pack
similar to Araldite) advertises "hard in 60 seconds" (I can just about
remember those days!) "solvent free", "dries grey", "can be sanded" etc.
etc.
It's a one shot system which expands to 500ml of foam. Just the job for my
dinged wing I thought so I bought a pack.
Tried it out last night - what a laugh - once you start squirting the
mixture you can't stop otherwise it cures in the special mixer nozzle - so
there was foam everywhere. However it did the trick even if it was mostly
wasted and I was able to sand it to shape no bother.
I've taken hmz6's advise and covered the LEs with packing tape.

cheers
