From: Dan Bergeron Hi Ed: Some folks prime and some don't - I won't go into the pros and cons - that's guaranteed to start a fight - I finished my -7A (a slow build) 3+ years ago - I primed everything with Sherwin - Williams Industrial Wash Primer - Semi Transparent Green (P60 G2) - I bought it at a Sherwin Williams store the caters to body shops and professional painters - I used an "el-cheapo" spray gun from Home Depot - my first efforts were a bit messy but only the bugs will ever see them - I eventually got pretty good at it - do not scrimp on respirators - get yourself a high quality, well fitting 3M or equivalent - keep all garage doors open and use a couple of box fans to keep the air flowing through - best would be to get yourself a fresh air respirator which draws fresh air into the mask through a flex tube from outside - the downside is they tend to be expensive - not sure the impact of ambient temps - I remember spraying in some pretty cold conditions here in Massachusetts - when finished I closed the doors, turned the heat on and got out of there - the parts dried just fine - hope this helps - good luck and enjoy the build Dan Bergeron RV-7A N307TB 376 hours since first flight on 8/4/09 On Fri, Dec 21, 2012 at 1:39 AM, R.C.

Just do what ever you want. In the end one can justify either decision. However, if you ever sell the aircraft, it might be diffucult to convince a buyer that bare aluminum is OK. Parts of my aircraft are now 20 years old. Only sign of rust is on the steel parts and they were primed and painted. My rollbar is the biggest problem, if I had to do it again, I would have it powder coated. Bob ________________________________ Message 3 _____________________________________ Time: 06:19:35 AM PST US From: David Oakes Subject: RV-List: Prime or not I just finished my RV7A and I alodined every part and then primed with epoxy then painted as needed. I found that if I painted some of the interior (in the front under panel) that the light reflected better and made under the panel easier to view. Just a thought I did a slow build fuselage also.
