Finish Kit

Filling pinholes in the fiberglass components must be the most unrewarding part of building an aeroplane. You have to question the intelligence of anyone who builds the whole thing this way!



I have tried everything for filling the holes. What works best for me is to mix up a thin cream of epoxy resin with micro-balloons. They are phenolic (?) balloons, and coloured brown. This is why it looks as though it has a rash. I spread it on with a credit card.

I use a slow setting resin so once done I leave it over night.

A small detail but it worked for me on the -9a I built, so I have implemented it here. This view is taken from on top of the engine, of the underside of the cowl, and the top of the firewall. I bonded a couple of offcuts off the cowl, to make a little clip to tuck the pins that run over the top of the firewall underneath.
