First color coat yesterday. Running into the nitrate/butyrate problem. No butyrate thinner. Suggestions?

Sig.com, Brodak, Penn Valley Hobby for thinner

For Yellow you almost always need a white under coat.
Don C25-Jan-14 16:36
Thanks Jerry, I'll remember that. A few more coats and I should be OK.
David Duckett25-Jan-14 16:41
A light brown or tan close to the yellow will work best as an underpainting, primer, and allow fewer coats of yellow.

Again, thanks for the help. I haven't done a silkspan covering since I was a kid. Long time ago! Figured that I had to use dope.I am going to check out your piece on acrylics on the Guillow's site. I used them on the P-40 for the nose art and it works well. I only do this in the winter when It's too cold to get on the horse, so my experience from the 50's is a little out of date. This site really helps.

Thanks David, I've always used white as an undercoat for yellow, but I can see that a light tan could be even better at times.
David Duckett26-Jan-14 08:43
If you use spray paint, white is a good undercoat as sprayed paint covers better. Brushed paint doesn't cover as well unless it's thick. That's OK for Van Gogh but not for models. I use several coats of thin paint and that requires an opaque ground (surface), especially with the transparent colors yellow, red, orange, and some shades of green and blue.

Suggest finishing your yellow paint job with a Krylon spray can.

I never paint with colored dope and I only have one color left, yellow, just like yours. Krylon has never failed me, the price is right and no spray gun to clean up!

OK, spent the weekend on every site I could find. Mr. Duckett, read your piece on Guillow's site. I really like your C-47. Now, can I spray Krylon over the butyrate? It would make life simpler. Or, if I can't find the correct color in Krylon, can I brush acrylic over the butyrate? Also making life simpler.
David Duckett28-Jan-14 08:51
Thank you. The answer to both questions is "Yes".
David Duckett28-Jan-14 08:55
Krylon is not the only choice. Liquitex also makes their paint in spray cans at about $12 per can.

Thank you! Off to the stores and then back to work!
