Top Tip for pinholes!

I never read this, or have been told it before, but the guy at my local paint shop gave me a great idea. I was complaining that fixing the last few pinholes appears to go on for ever. Up until now I have been trying to squish paint some days, filler others, into the holes with a credit card.

His reply was "Easy, take a pin and some paint, dab the pin in the paint and then in the hole." It works and it is obvious once you know. The pin displaces the air in the minute cavity, but when you pull it out the paint gets sucked in. It works!

Sorry if you already know......

And for the quote of the day, George Bush talking about Tony Blair.
"I've heard he's been called Bush's Poodle. He's bigger than that."

I hate pinholes as well as fiberglass!

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.
