I've learned no more on this than the following from a month ago....
Perry Casson
Just a short update regarding the report of Canadian inspectors failing
RV-10 wings on preclose inspection. Unfortunately I've still not got
names or kits numbers so I've not verified anything with the builders
but here's the info I've received:
- At least two kits were affected.
- All reported defects were under driven shop heads on the 5/16 rivets
on the main spars
- The problems were only found on fast build wings.
I'm got the calipers out to check my slow build spars and found all the
rivets were well within spec. as I suspected.
With the tanks off this should be no big deal to fix but I'd not be a
happy guy to get this flagged as a defect during final inspection.

Since I have decided not to build a RV-10, my engine needs a new home.
I have a O/IO-540 E4B5/C4B5 that is a match for a RV-10. This engine
can be configured with a carb or fuel injection - everything else
internal to the engine is the same according to the Lycoming data
sheets and Vans. 21,900$ for a first run Mattituck new limits overhaul,
2800TT, 300 SMOH. I had the engine back to Mattituck for a IRAN and
test cell run prior to my purchase. All accessories, starter, Bendix
RSA fuel injector, correct carb should you want to run a low pressure
fuel system, yellow tagged (RV-10/Rocket set up) prop governor,
governor cable stand-off and paperwork. Pictures available and more
detailed log data of course..........

I have run into a problem making my single stage self etching primer adhere
to some of the parts. At first I thought I had contaminated some of the
parts with bad acetone. I dumped the rest and started a new can. I have
changes to new cans of primer, replaced my scotch brite pads with new, and
started a new roll of paper towels. I scuff each part and then clean it with
acetone before spraying. This has worked well for the whole plane so far,
and this is my third plane. Has anyone else run into this problem.? I'm
starting to wonder if the aluminum is contaminated right from Van's. Problem
first showed up when doing the rear spar bulkhead and has now re-appeared on
the ribs that hold the seat belt anchors. Zinc chromate seems to stick OK,
and thats what I ended up using on the bulkhead, but I prefer to use the
primer.
I'm going nuts with this....
Thoughts.

I started out using acetone and found that it actually does a poor job
cleaning because it flashes off very quickly frequently leaving a
residue. Using a degreaser actually works much better, just about any
of the paint manufactures also make a cleaner/degreaser. I've also
heard of folks using naptha (Coleman lantern fluid) with good success.

Try some PPG DX-330 to make sure there is no residue.

Ted,
Assuming you are using the rattle can primers. I too noticed this.
One thing I noticed is moisture will affect the adhesion. If you take a part out
of an air conditioned space (Cool / dry) to the outside for priming, you need
to allow the part to warm up. As you prime it, the part will get pretty cool
as the solvent evaporates. If it cools enough for moisture to condense from
the air, the primer will not stick. I have found two methods to help with this
problem:
(1) Take the parts out to direct sunlight and allow them to heat up both before
and after priming. (It helps the drying time a bunch!) You can even set up
some heat lamps to warm up the parts outside.
(2) If you can't do 1, then do light coats so the part does not cool significantly.
Moisture seems to really affect end results.
You may have a different issue, but this is what I have found.

PPG DX-330 works great. But make sure you know what parts are what, because
you're going to lose your markings, which I just found out.
Watch out for water, either condensation or, if you're using a gun, do you
have a water separator...
My latest experiment however is to use the PPG DX-330 and that's it. No
scotchbrite or anything. If you've got alclad, the self etching primer
should bite in just fine by its lonesome. I'll let you know how it goes. I
just did a batch and primed it with the PPG 1791 self etching primer. Randy
Debauw recommended this approach after he talked with some folks at PPG and
that was their recommendation (Randy, correct me if I got this wrong), but
Randy used Acetone instead of the DX-330. We'll see.
