Thanks man. If I can get this clear figured out I'd shared a few. Guess I'm my own worse critic lol

Your probably holding your airbrush too far from the bait. Try holding it closer.

Ben is the man when comes to this product and the spray application. He didn't steer me wrong! I highly recommend his advice.

I am using a .5 and then tried.35 nozzle. Same results. My can of DN is also brand new. I'm stumped

A .5mm nozzle should be fine. Try thinning to something around a 40% mix of acetone to DN and hold your airbrush no farther than a couple inches from the bait. I usually run my air pressure around 15 to 20 psi.
I've had the "silly string" thing happen to me. I must have had enough acetone in my mix that I could spray back over it with the airbrush closer and it would melt the strings back into the finish.
Try the things I've mentioned and see what happens. I've found the "mix" to be fairly forgiving as I mostly eyeball it. Be sure you stir really well when mixing the DN and acetone. You shouldn't see any "swirlies" while stirring. It should be completely clear without any "ghost lines" of DN showing up as it's stirred. This might be hard to see as both ingredients are clear, but mixing it under a good light you can see any shadows created by the different viscosity of the two products.

Let me know how it works out Shaggy. If it's still giving you problems maybe we can work something out.

I have been wondering about this. Ben does it matter if the brush is gravity or siphon fed? I am using gravity but I was wondering if Shaggy is using a siphon type. Could any equipment that Shaggy is using be the issue?

I've used both Dale. Didn't seem to make any difference as long as the airbrushes were clean and spraying properly.

Let me throw these out there since I'm new at this product. I worked with the thinning and spraying DN. I found that at times I got heavy or to light on the trigger. The next thing that I am going to throw out here is contaminates in your air delivery system, compressor, hose including a semi blocked hose, brush. Where you lose volume and pressure past your gauge.
If contaminates is not a issue. Make sure you have proper volume through the hose. The problem is if it's a slight blockage it will be hard to tell other then using a gauge. Bring the pressure up a little and watch to see if that helps.
It is always something that you don't think of, if the product is a proven one. Well that's it for me.
Wish you all the best,

Thank you so much guys. Talked to Dick Nite yesterday. Going to use your advice and his and will find out this morning how it works. Will keep you updated on the issue.

Please, curiosity is up. I would like to know what it is.
@ Ben, While we are on this topic. I'm worried about my brush that I'm using for the application of the coating. I have only used it once and I cleaned it properly. I want to buy one dedicated for clear coating and get this one back with my other one for painting.
What would you recommend but not breaking the bank for DN? You mentioned siphon being used by you. I was thinking of this type because of the jar to hold the product. What's your or others opinion on this?

Good luck Shaggy. Hope you get it worked out.
Dale, I bought a cheap Harbor Freight gravity feed airbrush to use specifically for spraying DN. Don't remember exactly what I paid for it, but it was cheap. Figured if it eventually threw craps I wouldn't be out much. I've also used my Paasche VL siphon feed when there was several baits to coat at one time. More often than not I only build a couple baits at a time so didn't feel the need to buy a HVLP gun.

Ok, I have always painted a group of baits and that habit has followed me to wood carved baits. I believe I'm going with a mid range priced siphon type. I just couldn't stand losing a Iwata to a error or higher then normal wear and tear of the cleaning.

Much thanks to everyone. You guys are awesome. So taking a bit of advice from all of you guys and DN after a great phone conversation I decided to spray S81 without thinning it at all. We used a .5 tip with a psi of 10. Sprayed very close about 2 inches from the blades and put on a heavy coat. Sprayed roughly 250 blades and they are smooth and glass like. All blades had been dried for a week. If this finish is super tough like everyone says then this is how we will do blades from now on. In sure I'll have to thin an opened can that stars to thicken a bit in the future but for now in.happy with the results. In a week I will do durability testing.

Next time try "tapping the can" with a small valve. It will save product.
Glade to hear that your on your way.
Posted 19 July 2016 - 07:37 PM
I bought small jars to start. I will buy in larger quantities and have research tapping the can. I'm sure I'll mess it up but I'm gonna try.
