Do thin balsa strips need to be prepped in anyway prior to application on a board to prevent delam, etc. I was reading a post re: perimeter balsa stringers and there was mentioned needing to do something to the wood so the glass wood bond well. I haven’t seen anyone mention any prep or treatment. Bert Burger is definitley doing something to the balsa, but I’m just talking about a simple balsa application.
not that ive found , other than tape your pieces together and stick it on with cloth and resin
no prep required
