Hi Tom,How's your progress going on covering? You've seen the blurb of my progress posted to the discustion group. With this cool weather the bottom of the fuselage has become a problem to dope. Last night the bottom was re-sanded and another coat of dope sprayed but the same problem re-occured (blushing) so it must be cooling too fast. Another characteristic in some places is a powdery effect. This usually happens when the gun is held too far away from the surface. I held it closer but the same problem occured. At least this is the (last) bottom surfaceof the fuselage. Tonight I'll sand it down again the wait for a little warmer weather. I pulled out my propeller carving machine , set it up to get ready for the next job, and in parallel i'll be preparing the lift struts.Regards,Domenico Bellissimo ________________________________________________________________________________

The problem lies in the air coming from the aircompressor. You need a big drier to remove the moisture from the air.Them you will have no problems. You can spray when it is raining. Youwill need a drier about 5 feet tall and 1 foot around and holding half abarrel of dessicant. See Ted davis's at Brodhead.
