Brief Description: Primed and soundproofed, misc stuff
Today I shot some DP40LF on the floors and baggage door. Basically I am priming anyplace where water could sit and puddle but that's about it. The Alodine treatment will be the majority of my interior metal protection where I don't paint. Once that had cured I showed Amy how to spray on the QuietCoat soundproofing material. This can go a little slow because it is basically like spraying an undercoating. Very thick stuff. While she was doing that I messed around with the hinge for the hat shelf and rear bulkhead cover. I also cut the cover in half to form a door. The part that goes over the hatshelf will be held closed using thumb turn camlocks.
While I covered this subject in the past, I have had some questions around the soundproofing material. The material I am using for soundproofing comes from a company called www.quietcoat.com. It is basically a liquid form of the same stuff they make TempurFoam products from. When it's sprayed on and dries it gives a very good sound deadening effect through absorbtion in addition to the usual weight deadening. A quick primer on sound proofing. Basically all of the popular sound proofing products are a asphalt impegnated fiberglass mat. They are adheared to the exterior surfaces and work simply because of their density. Density = weight in this case and weight is bad in an aircraft. The QuietCoat stuff is a good balance between weight and performance. I also didn't want a product that could trap water between it and the aluminum. When this stuff dries it is very weather resistant.
