Looking through Sport Aviation and Kitplanes completions section, I havefound and contacted a couple of builders who have used Exterior Laytexover fabric.Last night I called Bill Brown, a Minimax builder who has been flyingfor 1.5 years with a laytex coatings. I gleened some very goodinformation from him that I thought I might pass on.Bill used the superflite system fabric and cements. The first coatingwas Benjamin Moore impervex Flat Black Exterior paint. This seals andfills the weave, and provides UV protection. The following coat was 3to 1 black to white. The reason for the mix is to provide a lightercolor base for light color coats. I have also seen one example of goingwith a straigh white for the second coat. Following are very lightcoats of the colors of your choice. Standard colors are best, becauseyou take your chances on custom mixes being the same shade if you haveto go back for more paint. Bill said that he used 5 light coats on theblue he used and 6 for the yellow.Concerning durability, Bill said that very small cracks were developingnext the rib cap strips. He did mention that the cap strips wereonly1/4" wide and there was no rib lacing. The airplane is hangared.Paint was applied with at foam brush in very light coats. I asked aboutfuel resistance and he said that it wasn't a concern, and that anon-petroleum based wax helps shed any spilled fluids.I plan on spraying this weekend. I guess time will tell if this isreally a good way to go.Any other tips or experience here? please post it!Stevee________________________________________________________________________________
