It's spray paint, not sue what you meant.
I was being a little sarcastic. It's extremely bumpy. Would not be happy with that surface profile on my rocket.

I clear coated a rocket with eggshell texture, I'll get a pic of it later today. Would eggshell finish be similar to a golf ball where a smooth surface is not the best for drag? I don't know, but now I'm wondering. You got me thinking and I sometimes like building MD rockets for max height. I just got a 23 Subaru WRX that has a hexagon texture on the bumpers and fender flares, Subaru claims the texture improves aerodynamics but that could easily be just marketing hype. It would've been cheaper to have a smooth surface, not sure why they did it. Wished I had a wind tunnel.If I understand @Banzai88 's post (#89) correctly, applying a coat of Max2K on top of Montana (or other any other paint that leaves an eggshell texture), leaves a smooth, high-gloss surface. But it strikes me that unless the eggshell texture is sanded smooth prior to application of the Max2K, you still have the appearance of eggshell texture showing through the Max2K. So, a smooth finish that reduces drag, but still appears bumpy.
Or am I missing something?
Thank you. for pointing this out. My next rocket will get weighed before and after paint. I do go heavier than I need to, especially for the rockets I fly with a Club. I have to be presentable around the guys who are 100X more experienced than I am.If you put enough clearcoat on the paint in the image shown above to level it without blocking it down first, that's a heck of a lot of paint weight. And expensive clearcoat.
I talk about paint weight a lot, but it's a consequence of figuring out that a body tube I'd painted weighed 9.# grams before paint and 19.# grams after paint. More than half the weight of that part of the rocket was paint, and my mass and c.g. calcs were blown all to heck. Big problem.

In some cases Montana isn't as glass smooth as some 1 coat enamels, but it's darn close, and has NONE of the issues that you all are complaining about with other mass market rattle can paints.
This is Classic Gray Krylon over white Krylon primer on a BT-80 tube, with a top coat of Pledge acrylic floor finish. The gray Krylon was not sanded prior to being coated with Pledge.

1 can will do 3-4 6 foot tall 4 inch diameter rockets
Pontiac did that with their Trans Am and Firebird beginning in 1970.Since you brought up the Subaru, the hood scoop on the STI, at least the original version, worked better if it was turned around to take in the high pressure air at the base of the windshield. At least that's what some racers told me back in the day.

The paint that I typically use will easily paint one rocket and I get good one coat coverage, but when you take the paint off the shelf for the second rocket it won't work anymore. I'm goint to start trying paint from ACE hardware, it seems to be better quality.it's a very cost effective way, since 1 can will do 3-4 6 foot tall 4 inch diameter rockets
Is the valve clogged or the can itself? I take the valves off my spray cans as soon as I'm done, put it on a can of glass cleaner and spray for a second to clean out the valve, then re-install on the spray can. This only works on female caps and aerosol glass cleaners like Sprayaway.The paint that I typically use will easily paint one rocket and I get good one coat coverage, but when you take the paint off the shelf for the second rocket it won't work anymore.

My theory is that it is a problem with the valve itself. I think some of the valves clog easily, but I also think some of the valves might have a very slow leak and leak out the pressure over time.Is the valve clogged or the can itself?

The MTN clears so nicely.
I am lucky as there is a blick close to me. Just picked up a few more colors today for 6.50 a can. Got some of the clear gloss as well.That's one of the reasons I decided to give MTN Hardcore a try. Next step was to find a retailer that had shipping charges I could tolerate. I looked at Machine Studio, MC Art, Max Warehouse, Blick, and Amazon. Machine Studio was the cheapest shipping. Just for grins, I clicked their Contact page to see where it would be shipping from. LAS VEGAS! They're a straight shot down Sahara Ave, 10 minutes from where I live.
My search for a good spray paint at a decent price is over. Woohoo!
Rusto 2x. It just works.
Where do you store your cans of paint.... and how do you store your cans of paint?
What type of Rustoleum paint are you using?
There's got to be a reason why you have so many issues with Rustoleum.... and I don't.
I use the default nozzle as well, never had a need for anything else, and I've painted 38mm min diameter all the way up to 4", no issues.A question for @Banzai88 , @Mightymango , @ShadowSpire48 , or anybody else using Montana/MTN Harcore paints:
Both of these paints have a dozen different size valves available. Is the spray pattern from the valve that comes on the can a good size for painting rockets (mine is 3' dia., 52" long)? Or do I need to get one that sprays a wider or narrower pattern?
Thanks!
