No light penatrates.It's in my basement shop with no vapors and looks real good.Dick N.________________________________________________________________________________Date: Sat, 10 Feb 2001 02:02:26 -0600

Okay, here's an odd thought: I visited the local Wal-Martyesterday and noticed something called "Liquid Aluminum"in the paint department. It's an oil-based (soybean oil)paint that appears to be mostly aluminum solids. Thelabel said "chrome aluminum" in one place, but my sensewas that it referred to the color. In all, it sounded a lot likea viable silver coat. Anyone know about this stuff? Anyoneever heard of it being used? It's of some interest, becausethe price was only $13 and change per gallon.Owen Davies________________________________________________________________________________

Just an FYI here.I've been reading up on aircraft finishes. It seems that the standard aircraft finish is nitrate dope with buterate dope over the top of the nitrate.This done, because buterate wont stick to polester fabric...WRONG !From what I have read, just about nothing will stick to polyester fabric. Not nitrate dope, not stits vinyl, not buterate, not house paint.. They all attach to fabric by mechanical lock.Mechanical lock :The dope...seeps thru the weve of the fabric, and attaches to it like the plaster and lath in an old fachioned house.The natural question then is, why must we use some special dope/paint if they all lock the same way, and if none of the finishes which I have mentioned will naturally block UV ?The nitrate/Buterate nitrate process....Nitrate dope does not shrink. It is painted into the fabric to fill the weave. Next a thin layer of buterate is sprayed on. Buterate shrinks.. a lot! If buterate were applied directly to the polyester fabric, in time,it would shrink excessively, distorting the airframe, and/or pulling itself out of the weave of polester fabric. IE: Peeling.So...nitrate is sprayed on first, then a thin layer of buterate dope.A thin layer of buterate, not a thick layer, for the same reason that a thin kid can hang on to the monkey bars better than a fat kid. There is more lock per mass.Thick layers then have less lock per mass.Ok, what does this have to do with house paint ? Well it seems to me, that if there is a problem with house paint on fabric, there would be two reasons why.1. House paint will not block UV. This problem easily fixted with silvar, ....or black paint. (My own choice would be silvar)2. Since all paints, aircraft type, and otherwise, which are used on polyester fabric, mechanically lock into the fabric...the problem with house paint, may be the same as the problem with buterate dope,,,that it may shrink, and pull itself away from the fabric, causing peeling.Some of the guys on this list seem to have used house paints successfully, so it seems natural to me that they will work, assiming that they won't shrink over time, peeling themselves away from the fabric,,,. And assuming that they can be made to block UV. And lastly that they will withstand fabric drumming.MY 2 cents, it doesn't make me right.Bob________________________________________________________________________________
