The rocket was room temp, and was the paint. Sprayed it outdoors and brought back in to dry. The rocket is STILL tacky. The PAINT was used properly and IS CRAP.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !

One of the first rockets I built when I BAR'd back in 1999 (an Alpha) used the 99 cent WalMart paint. It remained tacky for months it seemed.

When it comes to paint, I don't scrimp on price. After I've put more than a few hours into getting it ready to paint, I ain't using crappy paint that stays tacky or blushes easily. I don't want to throw away hours of work to save a couple bucks on cheap paint. I value my time way more than that.

Sounds like you do, too.

Yep. Quality costs money.
I saw the 96 cent cans next to the $3.98 cans of Rust Oleum and foolishly decided to try the cheap crap. NEVER again.
If DuPont Imron catalyzed urethane had not gotten so dawg-gone expensive I would use it far more. Nothing beats Imron for hardness, gloss lustre, and long life. A pint of just the 192-S hardener for Imron is now over $100 retail. Ridiculous.
PPG Ditzler Deltron for years was promoted as being just as good as Imron, but I have not found that to be even close.

I did my 1977 BMW in Imron. It is fantastic paint, but it has to be sprayed with a respirator, at least on cars!
Very durable and beautiful.

Allen

Many full-scale aircraft are finished in Imron due to the fact it is extremely tough, and retains gloss for a LONGGGGGGGGGGGGGG time even baking in the hot sun on the tarmac.
What's a respirator ??????????????
Dun't need nunn a that bunkola and guffery.

I worked in a Coca-Cola paint/body shop in the summer of 1983. We had the DuPont poster on the wall for their big four brands (Imron, Century, and two others I forget). The four honeys sitting on that Trans Am were incredibly attractive

Anyway, back then, a gallon of Imron was 80 bucks. We put that on our Coca Cola trucks. I had hot rodders telling me we had the best looking trucks in town We put the Century on our soda machines.

No doubt, if you use these kinds of paints, you'll have some beautiful rockets. But keep in mind, not only are they expensive, they don't come in rattle cans. So, on a typical rocket, you'd be wasting more paint loading and cleaning the gun then you'd lay down on the rocket - it'd be super expensive!

In all seriousness, many of today's 2-part paints are extremely hazardous, not only to breathing, but also to touch. They're applied wearing dang near full hazmat gear.

I don't think the label warnings for this stuff are namby-pamby lawyer CYA talk. I take them pretty seriously.

C'mon, GH, read the label on that stuff, then tell me it's not bad for you. I know you know the chemistry side of this very well!

I was just joking there.
At worst I sprayed small amounts of Imron with a chemical mask outdoors without a respirator. If I did an entire car or aircraft (including R/C) I would use a respirator. Catalyzed Urethane is nasty stuff due to the isocyanates in the catalyst/hardener. it is not a question of if you will have a reaction to the stuff, it is when.

On the other hand, I use no protection when spraying/brushing dope. It is just a little Toluene, MEK, MIBK, and Acetone, of which only Toluene is even moderately toxic. Wearing all that crap IS mamby-pamby for that.

The four major brands of Dupont Paint were/are: Imron urethane, Lucite lacquer, Centari enamel, and Dulux enamel. There was Duco lacquer also but ended in the early 70's. Lucite and Centari are top-tier products, Dulux and Duco were the economy ones.

Years ago, the Tempo brand touch-up spray bomb cans contained genuine DuPont Lucite lacquer with LEAD pigments well into the 80's !

How much is Imron nowadays? It was expensive back in 1980!

Allen

For 'basic' Imron the Activator is about $100/quart and the actual paint is around $100-125 for 3 quarts depending on the color. Mix together at a 3:1 ratio.
For the Imron "Elite" line, colors START at about $200/3 qts, PLUS needing still $100 of Activator. NOT cheap.

Those prices are INSANE for a gallon of solvents, hardener, urethane polymers, and pigments. No new tech there, just pricing insanity like most small specific purpose goods nowadays.
