Excuse my smart ass, but I thought you were an old time experienced modeler!! You really think Lite coat means it's light dope? Just had to ask as this is something that has been discussed on here more times that how to set up your FP-.40 for stunt! SIG Lite Coat is low shrink dope. Most use regular SIG butyrate for the first few build up coats to get shrink, then finish up with Lite Coat to avoid over shrinking. All SIG colors are made with Lite Coat. And Lite Coat is butyrate dope and not any more or less fuel proof than anything else out there. It has been around as long as SIG has.

Oh, then I have another question about Lite Ply. Is it low shrink wood?
Of course not, look at it next to normal plywood. It is several shades lighter. LL~

You have to admit the lite coat name is a bit deceiving. Should be called "Sig Low Shrink" or something like that.

No, I don't have to admit it. Lite coat has been around since the Dead Sea was sick and since SIG has been selling dope! It has been described in countless articles . adds, and in detail in SIG catalogs on how to use their dope products and should be on their website. I can't tell you how many times it has been explained and detailed on just this website alone. I believe it got it's name from it's primary use, doping light weight free flight air frames. If you have ever read free flight articles or kit instructions, they almost always called for " a light coat of dope" on the structures when getting to the point of doping the covering to avoid warping. Before Lite Coat, they advised adding a few drops of castor oil per ounce of thinned dope to plasticize it and make it non tautening. Then there is ALWAYS the oldest trick in the book, try reading the label D>K H^^ It says "Fuel Proof, Low Shrink Butyrate." And I guess I had better not tell you about banana oil. No, it's not for quieting down squeaky bananas!
