Craig:
I saw the picture of your Q in Q-talk. I would be very interested in some better pictures of the interior, in particular the brake handles and their set-up, cabling etc. I need to do something like this for my Q soon, and like the setup in yours. You can e-mail me directly. Thanks, Dave R. Q1 Texas N4YQ

Re: No More Sun Bumps ( or finding the neutral zone )
Kevin Boddicker <trumanst@...>
Richard,
toggle quoted messageShow quoted text
I used UV Smooth Prime from Poly Fiber. It is a catalyzed water born primer applied with a foam roller. I followed with their epoxy primer and top coated with Aerothane. The foam roller fills "most" of the pinholes due to the pressure of the rolling process. It requires six coats, as per the directions. Sands very very smoothly with 320 grit, if you get on it in several days. After a week or so the primer gets too hard to knock down with 320 grit. So 180 will knock it down, and the 320 will smooth it up. The most important thing is to stay with one manufacturer all the way through. Conversations with the Poly Fiber factory also told me to let the epoxy primer cure for at least 48 hours. If not cured the "gas" from the primer might bubble under the Aerothane. If longer than 48 hours the epoxy primer may need to be lightly scuffed before the Aerothane is applied. My paint was applied in the fall of 04. So far so good. Hope this helps Kevin Boddicker Tri Q 200 N7868B 45.7 hours Luana, IA.

Re: No More Sun Bumps ( or finding the neutral zone )
aerofxinc <aerofxinc@...>
hello guys,
I haven't read the messages in quite a while and have just caught myself up on the paint issues. I am a professional aircraft painter (20 years) and have had my own shop in Fl for seven years; Aero FX. I have painted my share of composite aircraft and I would be happy to help anyone with any questions. From what I've read there seems to be a question about "the black". I'm guessing this is a UV barrier applied at construction. Depending on the type of paint you are using, many newer generation (last 10 years) paints have incredible UV protectors built in. Paint, like the fiberglass on your planes is a resin. Resins are UV sensitive meaning they can be cured by UV rays. Many paints become faded and brittle over time due to the continual curing effect of the sun. Any paint that says "photochemically sensitive" on the can will require a UV base under it. If you have paint already and can't tell, place some uncatalyzed paint on a stirstick and put it in the sun. Most will cure over time but some designed for aircraft use will not cure until catalyzed. These are generally polyurethanes like Jet Glo. It was also mentioned that "gassing" and moisture might be culprits and both are true. Any materials with a poly base are moisture magnets. Make sure to keep your booth, hangar, etc. warm and dry. For gassing, let the product cure out before covering it with something else. Many hi-build primers are poly based and take a long time to cure out completely. (30 days @ 70 degrees) Shrinking is also limited by curing time. That's when you don't see the glass weave after priming and sanding and then it pops up after you've painted and flown for a month! Patience is the only answer. I'm sorry for such a long post but paint is a laboriuos and very meticulous process if you are to expect good results. I am available to answer what I can via this discussion.

The better the prep the better the finish. I am using PPG. Whatever you use make sure it is all the same product after the two part primer/sealer.

Richard,
I have my sparrow strainers mounted just behind the middle hinge support of the elevator, as indicated on plans. I asked the same question this fall, because I noticed most Q2/200 have the strainers mounted close to the fuselage. I was told that the "close to fuselage position" takes advantage of prop wash.

Re: No More Sun Bumps ( or finding the neutral zone )
Mike Dwyer <mdwyer@...>
You need the UV barrier, remember Gore says the Ozone is gone and you don't want your plane melting in the hot sun. Also the paint that peeled off mine was also black on the bottom. I don't think it was so much that the black split. I think it's the out-gassing of the fiberglass that pops the paint off and the black tries to stick to everything... I left an unprotected piece of fiberglass in the sun and after a year the resin was gone leaving only the raw glass. Seems the resin sublimates (solid to gas) in the sun?

Thanks for the tip. I am using PPG DP90LF two part black primer. Since it is also a UV barrier and is appropriate for PPG finish coats, I will be using it as the final primer. Hopefully, I will have fixed all defects. If some defects do show up, I will give it a try.
Perhaps your primer to primer delamination was casued by using different brands of primer or inadequate sanding prep.

It bonds tight and is easy to sand ready for paint. I tried a small tester and it seems to work quite well.
