Ok, I read the entire Talc post and several folks mentioned using cornstarch. Well I've never used anything but premixed sanding sealer so I don't know the proportions.

Any help would be appreciated - I really want to learn how to do a decent finish and I've got two Twisters on the board and almost ready to start with the covering/finishing.

I'm going to brush on the mixture so how much dope, thinner, and cornstarch in the mix? How many coats of that do I do? I know I have to sand most of it off each coat.

Also I don't have any spray equipment nor a place to do it so I am stuck with brushes. Any hints on brushing rather than spraying will also be listened to and utilized.

Thanks in advance for your help.

Thanks Ty - I'll try this as soon as it gets a little cooler here in the 'Lou. Gotta work in the garage where there's no AC.

Did you know that newsprint was used at one time to buff out finishes?

Hello Ty,

Where is Lovelock? There used to be (and still kinda is) a town out here in N. CA called Lovelock and there was a local paper of sorts called The Miner. Not the same place?

And then there is the hand rubbed finish, where you just rub the finish with your bare hand until it shines. Try it, it works. don't think I would do an entire airplane that way--take forever.

I am gonna try the cornstarch filler. I have a box of Argo type filler, I mean starch. I will post a pic of the happy mess. I hope it works as good as it sounds like it does.

You want to be a little careful about putting it on too thick. It can crack on you as the (even non-tautening) dope shrinks.

Thanks for the tips guys. I should have some on by tonight. I had forgotten what the thickness should be. Had to say "pancake" didnt you, now I am hungry for pancakes...

I should have a pic up tonight, of the fues, not the pancakes.

I tried the cornstach filler. it worked great, and I'll use again. I only goofed in that I made it too thick. I guess I missed the part about "runny" pancake batter. I made like pancake batter. I had a ton to sand off, and I did sand it all off. Everything was real smooth, but then I got into the silkspan. So after I fixed the "sand thru s" I weighed the fues, 10.8oz. Ouch! I took it all back down to bare wood, and am starting over. Weight is now 9.1 . Thin is what I'll make it next time. I would post a pic, but they didnt show anything close to detail. The parts looked like they had cake frosting on them. I shoulda quit while I was so tired, but didnt want to waste quality drying time while I slept. Mistake.

Things are back to "normal" for me now.

I use blue ink in all my nitrate and filler. Just enough to tint it. When I am using silkspan on a fuselage, it gets three coats of notrate, sanded after 2 and 3 to knock down the grain, then I put on the silkspan. The filler comes next. I just never put filler on the raw wood if I plan on covering the wood. After 8 years, there is no grain showing on my Geo Juno.
