Thinning paint

I recently tried to touch up the paint on my Maule. The paint went on
fine and seemed ok. I flew yesterday in IMC and rain. Most of the touch
up eroded away in under four hours of flying. The factory paint is ok.

I thinned the paint 50/50 with VM/Naptha. It flowed and stuck ok. Any
suggestions on another thinner that would make the finished product
harder? Would a heat lamp after partial drying help?

Go back to where you got that and buy the thinner for it. Auto paint comes in a
variety of formulae and it's best to buy thinner made for that paint by the same
manufacturer. Depending on the formula, you may also need a hardener for it.

For the usual oil based paints used on home projects, mineral spirits is better
than naptha. MS has an oilier formula. For this reason, naptha makes a better
cleaner.

You stil don't say which of their paints. For the TEC/One and
Tec/Glo urethanes theysuggest thinning with their matching retarder.
For Tec/Plus they suggest acetone. All available presumably at
your local NAPA store.

Ron,
I do not know. I was given a pint of the stuff when I bought the plane.
I will try my local NAPA store and see what i can come up with.
Sounds like I need a course in automotive painting.....

George,
sounds like a trip back to the factory is in order. They gave it to me
when I bought the plane ( ok I had to ask for it).

Interesting. You bought that when I bought mine, didn't you? ('95). They were
using Randolph enamels at the time, and that's what they gave me for touchup.

Anyway, any good auto paint retailer that handles Seynour should be able to help
you out. Just take the can along.

I had some cracks in the paint and I tried dope thinner on the paint on
fabric fuselage and it just did not work..... I called the factory and
they told me they had switched paints that year.
The trouble around here is finding a store that handles Senour paint.
They seem to be scarce in my area.

I spoke with the Randolph rep. at Oshkosh a few years after I bought mine. He
said that old B.D. set up the painting method there. They shot the fabric with
silver dope. Then there was a layer of white primer -- he implied that that was
also dope, but I don't recall him saying that in so many words. Then they
applied color coats of enamel with plasticizers. Doesn't matter what the paint
manufacturer was, that was the method.

Now, enamel doesn't work over dope. Never has, never will. It gradually shrinks
and cracks. In severe cases, it'll crack the fabric. No amount of dope thinner
or rejuvenator will help. The Randolph guy said to either redo the whole plane
from scratch (that's what Ray Maule will tell you to do) or to sand off the
enamel layer, apply rejuvenator to the dope, and paint with either dope or
polyurethane.

After B.D. died, Maule changed over to using polyurethane top coats, but they
didn't throw away the enamel they had in stock, so there's about a 2-year
transition period in which you could've gotten either type of paint job.

On of the few things I don't like about the people at Maule Air is that it's
like pulling grizzly bear teeth to get any info at all about the paint on an
older plane. I think that everybody there knew it was a lousy system but nobody
wanted to say anything bad about the old man (even after he was dead).
