This material is designed for fillet sealing of fuel tanks and other aircraft fuselage sealing applications.

I ordered in a weekend and needed my purchase by a certain date. I was told when I ordered it would arrive on a specific day. And it sure did. Thanks so much for the great service.
Excellent product - be sure to shake-mix prior to use, the solids fall out of solution pretty quickly. So far we haven't had to use any reducer. This product is exactly what a well known structures rebuilder located in Indiana uses.
Great price. Prefer a hard copy...but printing from FAA website is not practical or what I was looking for. This periodical is perfect to replace my 15+ year old version. Love that Pilot Head Quarters had it on sale.
