Chapter 25 – Wing primer start

Today was all about getting a good bit of primer laid down on both wings.  Thankfully I was able to meet my goal in doing that.

In the continuation of my “combat painting” to get this bird flying, I went ahead and put plastic under the inverted right wing and then prepped it for epoxy primer.  Besides being inverted, the difference between this primer shoot and the left wing is that I left the rudder installed in the winglet.

Here we have the BOTTOM of the right wing, the inboard and outboard winglet with rudder all in primer.  If you’re looking at the middle and inboard wing areas and thinking that I’m a horrible with a paint gun, the white peaking out is the remaining boat paint primer… which will get a sealer to transition to top coat vs the epoxy primer shot here.

Here’s a better shot of the outboard winglet and rudder after 2 coats of epoxy primer.

Along with the right wing underside, I also shot the nose hatch door, the top cowling’s oil check door, and the right strake hatch door with epoxy primer as well.

Here’s a better shot of the nose hatch door.  While it looks great in the pic, there are a view visible imperfections (mainly along the edges) that will need addressed before the top coat can be applied.

I’m jumping ahead many hours —after I stowed the right wing in the shop for the evening— to grab a shot of the primed right inboard winglet and rudder.

And a shot of the right wing’s leading edge after primer.

Here we have the bottom the right wing in full view with the canard topside after I sanded away most of the high build 2K primer.  Also shown is the outboard left rudder also with its 2K primer sanded (pic 1).

I then flipped both the canard and the rudder to show the other sides with the 2K primer sanded to shape (pic 2).  I can say that both canard and rudder are VERY close to final contour for final primer and paint coats (while the wing will need a bit of work!).

Later in the afternoon (early evening by the time I got started) I finally got the upright left wing prepped to receive a couple coats of epoxy primer (pic 1).  And here is the result of that round of paint gun slinging (pic 2)… and although I could spot a number of areas that will need to be tweaked, overall I’m VERY happy with how the left wing and winglet first coat of epoxy primer came out.

Here is a shot of the outboard left winglet with 2 coats of epoxy primer.  There are some runs, since I was trying to balance lighting and viewing angles vs keeping the bugs off of it (it is the initial coat of primer so no major issues on any of that).

And a wider angle view of the left wing top surfaces and winglet in epoxy primer.

And a parting shot of the left wing top side and winglet in epoxy primer.  This pic has a good view of both the leading edge and the wingtip-to-winglet leading edge interface.

Tomorrow will be more sanding and hopefully more primer shooting as I attempt to get this bird painted ASAP.

Moving onward!

Chapter 25 – High build 2K primer

Jess and I are back from our whirlwind west coast trip, arriving back home around midnight last night.

In my push to get this bird painted, I’m employing some tricks from my buddy Nate Mullins, who I’m sure a lot of you have seen his awesome Long-EZ that he finished 10 YEARS ago! (wow, time flies!).

Anyway, for filling major divots, scratches, blemishes and general assistance in leveling out the surfaces being painted, Nate used a cheaper but highly rated high build 2K urethane primer from TP Tools [to be clear, this stuff is ALL he used to “paint” his bird as he flew it in just primer].  After our conversation a few years ago, I found it on sale and nabbed a couple of gallons of it.  Here it is with my 1.7 tip gun that I’ll be shooting it with.

Now, I know the gurus on high and the purists would/will excoriate me once they find out I’m mixing paint systems… and that I’m not going with the the only “authorized and acceptable” paint system mix: Awlgrip epoxy primer with Emron paint.  But I’ve talked to a number of very knowledgeable paint ‘gurus’ and they have blessed my “plan.”

I’ll start off by noting that most of this 2K epoxy will be sanded away and only the bit remaining that is filling in the blemishes will be left on the parts.  Any further blemishes will be filled with a compound prior to the final coat before paint, which will be a white epoxy primer coat.

Here we have the low spots and blemishes on the top left of the canard shot with 2-3 coats of high build 2K primer.

And here is the right side of the canard, again with the low spots and blemishes shot with 2K primer.  I also did the underside of the canard as well, but alas, no pics this go around.

Here we have the OUTBOARD of the left elevator and the tops & leading edges of the elevators shot with the high build 2K primer.  Again, most of this stuff will get sanded off.

But out of curiosity, I checked both the left and right elevators’ top contour… looking pretty darn good.

Here have the tops of the ailerons prepped for the high build 2K primer (pic 1).  See all those light areas?  Those are the high spots, so when I sand these again the surfaces will be much more level.  I then shot the TOPS of the ailerons with the 2K primer (pic 2).

I’ll note that the bottoms of the elevators and ailerons are not getting the 2K primer and are all ready for the final seal coat with white epoxy primer before final paint (1 coat for bottom surfaces).

Here we have the INBOARD of the left rudder hit in just a few areas (top & TE mainly) with 2K primer.

I also spent almost half an hour sanding the bottom cowling, and plan on hitting that with the 2K primer tomorrow.

Pressing forward!
