Short of White

Living in the boonies has its advantages. But access to a good hobby shop isn't one of them. They are out of SIG white and won't get any in for over a week. I need another 2 coats of white on the plane.
I checked at the local Home Depot and they have Rustoleum White that appears a good match. Will the Rustoleum work over the 5 coats of sig white? Help!

Hey Norm,

Sig dope takes forever to gas off. I would wait a month before painting anything differant over Sig dope.

With Brodak dope I only wait a week. (When painting auto 2 part clear).

Next time try to stock up a little better.

Call SIG and have them overnight you some white dude. May seem extravagent, but what's 10 bucks over the season of your new ride.

Stocking up is good advice. I actually thought that a 16oz can of White was stocking up..but I was wrong. Thanks for the " gassing off" info.

If you have an auto finishing supplier close by, you can allways go in and order a pint or quart of white (Or any other color.) but tell them to mix it without the binder.

They'll think youre crazy but what you'll get is a can of the correct color pigment, without any 'paint'.

Now, go home and add clear dope and you'll have whatever color dope you want. You'll probably have to pay full price whether you take the binder home or not but you can get any color you can find in thier color book. Want your new plane to match your car? No problem!

An added benefit of this method is that you will have much more pigment in your dope so you will experience much improved coverage with fewer coats and less weight.

Sig dopes are notorious for poor coverage. Especially the yellow and white. The introduction of Brodak's line of dope solved this problem to a great extent but the color pallet is still limited.

If you use custom colors, allways label your leftovers and put them away. You'll need them for touchups and repairs!

By the way.... This is a SECRET. Keep it to yourself!

How much clear dope to pigment? 50:50?
And then can you thin it down if needed?

Thanks

Paul,

As a general rule, the auto paint mixers put the pigment in a can, mixing it as they normally do but leaving out the binder. Just fill the can the rest of the way with clear dope. A pint can will be from a third to half full of pigment (sometimes more, depending on the color mix). Just fill it up the rest of the way with dope, shake really, really well; mix with reducer (thinner) and shoot.

edit---note: while I've done this successfully as have others, your milage may vary. I'd get some cheap white from the paint mixer and do a test first.

note 2: this ain't cheap. A pint of auto paint color can run from 4 or 5 dollars for a color inexpensive to mix (common ingredents) to $150 depending on the color you want. My local paint guy told me a pint of Lamborgini metallic yellow tricolor runs about $118 to $150 depending on they paint type (low end Omni versus high end pPg) The charge is the same whether you take the binder or not.

I won't tell a soul. Thanks.
I'm off to the auto finisher this AM.
I'll let you know what happens!
