Endura spray bomb

I'm not sure if anyone here has tried Nelson water based polyurethanes, but I had some killer finishes with nitro protection up to 45%. I haven't gone any higher and raw fuel can spill on this without damage. The material has literally no smell and this can be done inside. The paint thins and cleans up with water. The paint will run easily, so practice is required and not all parts should be painted at once. You can paint a side making the lap strokes in an inconspicuous area. It catalyzes chemically with a cross linker and dries to the touch within 15 minutes. The paint takes a bit of practice, I use a sponge brush that results in finishes that you would've thought to have been sprayed. It takes several coats, up to 5 due to the paint going on in a watercolor fashion eventually revealing a deep color. I found all colors including black work better and take less coats with white under them due to the paint being semi- translucent. I've flown the following day with no issues. I use the clear as a top coat with the crosslinker. Without crosslinker, the paint is fuel proof to 10% nitro. The paint can be used and returned to the container assuming no crosslinker has been added. The colors match Monokote better than any paint I ever found and John the owner matches Ultracote colors as well. The colors mix excellent together to provide additional tones.

It seems once you exceed 50%, just about all hobby craft style paints turn into a big smeary mess. Done with the hobby paints. A fresh spill on any of those and your wipe rag pulls all the paint off. Imron auto paints are in the research folder as well.

I used a lot of Imron on full sized planes. I think it was 5000 series. It is readily commercially available. It is a fairly easy paint to use, pretty forgiving and quite durable. I can not say how it holds up to nitro, though. The supplier down here got really stingy with the reducing agent, probably to adhere to VOC requirements. A little extra reducer goes a long way in getting that glassy finish with Imron. If you try it good luck. I hope you like it.

I put together a tutorial on posting pictures right here. Its easy to do!

Well, the stuff i have skimmed over today indicates that Imron holds up to high content nitro.

Decided to give the Klass Coat epoxy clear a try. Two part mix with reducer for my 1.4mm HVLP gun.

On it's way!

Thanks Paul! So I take it from your up above post that that plane was painted with the Endura 2 part mix with reducer for a spray gun?. If so, it turned out very nice.

Thanks for the kind words.
Yes indeed, the model was painted with 2 part Endura black. The trim was Endura flourescent orange + a clear coat. (Flourescents require patience to mix because the part "A" is extremely thick & takes a few minutes of stirring to mix with the part "B". Goes on flat requiring the clear coat to bring out the shine.

Well, The Klass Coat clear went on good. I went with a 40 min induction with a 20 min wait in between coats. I mixed up waay to much product though for a HVLP gun, but the way I seen it it was my first time with a HVLP gun and I would have rather had to much than not enough. I have used a convectional pressurized spray gun,,so I was thinking along those lines as far as quantity.

I used 5 oz of the gloss catalyst, 5 oz of the resin and 3 oz of the #500 reducer mixed in after the induction time. Once I got a nice pattern out of the gun, it laid on very nice. 2 coats on the boat. I had 5 oz of product left over after coating my boat stand with 2 coats. 25 PSI at the gun air inlet with the trigger pulled. 72-75° consistent painting/drying temp. About 30-40% humidity as per my old swing gauge. 1.4 mm tip Home Depot/Husky Green ring HVLP gun.

I painted the boat with Top Flite Lustercoat primer and color and let it sit for about a month before clear coating with the Klass Coat clear. So far so good,, no paint lift,,and rock hard.

What are you folks who use Imron using for face masks? I know at one time forced air masks were recommended.

Using HVLP equipment and spraying at 30 psi max, usually between 20-25 psi, and painting in a hangar with a good airflow I would spray for up to one hour a day with an old style respirator with two screw in canister style filters made for painting. Painting was just an occasional task and forced air masks and suits were not available to me at the time. If it was a full time job then forced air equipment would have been necessary.

Maybe exposure to paint fumes is why I can be so damn dumb some times, though.
