I was also under the impression that butyrate dope was fuel proof. I just went out to the shop and looked at a few cans of Brodak butyrate dope and it says "fuel proof" right on the can.

Having used the real Stits covering on a real airplane a few years ago, I thought I would tryStits-Lite onmy latest project, a GP .60 Extra 300. I currently have all the fabric on and one coat of "Poly-Brush" on the wing and fuselage. The learning curve has been very short and shallow, and so far, I really like this process.I plan on using Poly-Tone colors and clear for the final coats - It looks like butyrate, smells like butyrate, and acts like butyrate, so I just assumed it would be fuel proof; however, I could not verify that by looking on the website or on the can. Perhaps if Chip Mull happens to catch this thread, he can comment on the various Stits products and their ability to fuel proof a structure.
