I just located your card from Sun & Fun.

We had talked about citrus based solvents replacing MEK. There are two I
am aware of. One is Citra Safe which is made out on the West Coast. I
will get their data next time out to my hangar at the airport. Their
product is used by Boeing and the military as a degreaser. Main problem is
that it is expensive! The company only sells 5 gallon minimum. I bought 6
gallon cans and it was $350 with shipping. With all the degreasing to do
(we are priming entire interior) I evaluated the health risks as worth it.
In use it is nor uneconomical as the evap rate is much slower than MEK.
Parts need to hang overnight but Citrasafe is totally volitile. It is non
toxic and biodegradable. I use Invisible Gloves and vinyl gloves as the
solvent action will destroy latex exam gloves and the solvent takes all the
oils out of your hands. I have been satisfied with the performance as a
solvent leaving no residue. There is a product called Enviro Klenz from
Ammettra Inc. at P.O. Box 936, Baldwinsville, NY 13027, phone
1-800-651-1919, which claims similar properties but is not "aviation"
rated. It is 100% volatile and also non toxic. The flash point is greater
than 150 degrees. Price is right as well. Last time I asked it was $3.50
/ quart or $35 / 5 gallons, plus shipping. If I had it to do over I would
go with the Enviro Klenz.

Please send me the address, email, and phone for Dave Fife so I can replace
my fiberglass parts with better quality.

We had also talked about aluminum clip nuts to fasten access covers but I
had elected to go with Rivnuts and nutplates. Enjoy the Ramble. Sue is
retiring in 9 days so we will be able to make some real progress on serial
611E. With some luck we can Ramble with you next year.
