Gorgeous Roadster. Everything just looks right. Nice mix & match of parts, and a row of carburetors is always cool. Very nicely done.

The door handles are a fantastic detail. Well done!

A quirky 'anorak fact'; Sears-Roebuck sold the Henry J through their mail order stores in 1952-53. The cars were re-branded Allstate, and had some minor trim changes, but was otherwise the same car.

Nice work, Misha. Very cool subject, and well executed. You captured the look nicely. Well done.

Very impressive, Dan. Excellent work.

Great looking Merc! Beautiful car, nice detailing. Very cool.

Cool chop! Nice lines.

Cool project, Kurt. Never even knew this kit existed. I'm following.

Great looking Mustang. Understated and very cool. I like it.

Exceptional job on this old kit. Your paint and foiling look great, and nice clean detailing overall. Beautiful Charger. Very nicely done.

Excellent. My favourite F1 car. I’ll definitely be watching this build come together. I’ve been curious about this kit, too. A quick scan of the photos, it looks good.

Good looking modified, Bob. These are really fun kits to build. Nicely done.

Cool 70s vibe on this build. Nice colour choice. Well done.

I am seriously digging your Escort. Cleanly built with fine detailing, and the Lotus Twin Cam is a great choice and nicely done. It sits just right, and the wheels are a good choice. This is one of the coolest builds I've seen in a while. I love it!

That's the gist of it, though the physics minded among us will quickly point out that in both cases the paint is being pushed out. The mechanism is different though, where the airbrush operates at a much lower internal pressure, and I think that is the key. The lower pressure inside the airbrush allows the gas to readily escape, and it happens at the point where the paint and air combine, destabilizing this delicate balance. A siphon feed airbrush requires a stronger vacuum signal (lower pressure) in the chamber than a gravity feed, as it has to not only move the paint, but has to provide the motive force to first lift it up from the bottle, so the problem is worse with a siphon feed. I believe this is also why external airbrushes are less susceptible to this phenomenon. There is no mixing inside of a low pressure chamber, the mixing all happens outside of the airbrush, though the venturi effect is used to do this in all airbrushes. With the external airbrush I suspect that there is probably still rapid de-gassing at the point of mixing as the lower pressure of the venturi is encountered, but the dynamics of the external mix does not significantly destabilize the mix. That's my take on it anyway.

Hi Michael. See my Nov 17 post in this thread, about half way down the first page. I incurred a de-gassing induced failure every time when the paint was not given time to de-gas. So have others over the years. Like many aspects of painting, there are many variables that can effect the degree to which problems will or will not be experienced by an individual. I think your suggestion that there will be 'absolutely no problems at all' is a slightly short sighted because some experienced painters have incurred problems of this nature. Indeed, it is why the OP, a highly experienced builder himself, started this post. So the fact is, in some circumstances, it can happen.

I think it has to do with the dynamic of the paint delivery. Inside the can there is a high pressure atmosphere which pushes the paint out of the can and through the nozzle. The paint remains under pressure and has no chance for gas release until it leaves the nozzle. With an airbrush the paint begins to flow when a low pressure is induced in the mixing/venturi chamber, putting the paint in a condition of lower pressure right away when the trigger is pressed, and considerably more so when it incurs the low pressure of the chamber. This lower pressure tries to 'pull' the gas out of the paint, or perhaps more accurately, gives it a stronger incentive to leave the paint. In both cases, paint flow is induced by a pressure differential. I think the key element is that in the can, the paint flows due to a pressure 'up stream' of the paint greater than ambient pressure. In the airbrush, the pressure differential is due to a pressure lower than ambient pressure 'down stream' of the paint. This reduced pressure in the airbrush chamber causes the gas to escape the paint in volume, screwing up the flow dynamics with the airbrush and generally making a bubbly mess. This will be much more of a problem with a siphon feed airbrush than a gravity feed, and may pose even less of a problem with an external mix airbrush. It's worth noting that even with a spray can, the problem can still exist. Sometimes, especially in grooves and crevices where paint build-up is significant, tiny pin holes can be spotted when the paint is dry. This is due to de-gassing.

Nice model. Well deserved award. Congrats.

Most of the purchased holders used on the forum are from Tamiya From what I understand, the Tamiya stands are quite nice, though I've never used one. Most guys improvise some type of holder. Mine is fashioned from a wire coat hanger. It's pretty much what I've been using for the last 40 years. If I was home right now, I post a photo.

Nice fab work on that chassis.

Beautiful Vette, Bill. Very clean, and the wheel choice gives it the perfect period vibe. Very nice!

Nice fab work. Well thought out and well executed.

Cool pics. No less than three Henry Js. My fave is the red flip front. The two tone green Pontiac is cool, too.

Good looking Mustang. Nice clean build with great looking paint. Looks good with the decals, though when I opened the thread and saw the naked body, my first thought was to commend you on your restraint by not using the decals. Either way, it looks great. Well done.

Nice chop! It looks like a tough car to do a pleasing chop. Well done.
