Default Rust-oleum spray enamel won't dry!

I've got a piece of painted metal that I roughed up and sprayed with Rust-oleum spray enamel....2 days ago. Sprayed outside, and quickly brought inside where it's warm. 2 days later after drying in 70 degree house it's still tacky and wet.

someone told me it was due to their new "green" formula....anyone else haveing trouble with paint not drying?

I know its contrary, but I never use rustoleum and hate the drying time.
I use krylon or I don't paint it.

I used rustoleum spray cans for probably at least 20 years, until last year. They did something to the product and or spray tip in that they plug up and quit with 2/3 in the can. I had several cans all do the same thing. In the past when finished I've always turned the can upside down and sprayed inside a trash can until the paint stopped, then wiped the plastic nozzle and it was ready to go the next project. Not anymore. I started using Krylon some time last year and haven't had those problems.

Does not cure well in low humidity I believe to be the problem.

If they are small items bake them in the oven.

I sprayed my blue metal brackets for my shelf flat white then baked them for 285 degrees for about 40 minutes. Came out quite well. :-)

I have not had good luck with Rustoleum spray paint recently. Their nozzles are crap!

The data sheet says humidity needs to be below 65% for proper drying. Under "normal conditions its pretty slow to dry. It has mineral spirits. The MSDS for mineral spirits lists its flash point at 100.4F. Could to be why it drys slowly and needs lower humidity.

isn't that a big no-no? I've read that the residue from burning the fuel creates fisheyes in paint

For years I always have that slow drying problem with Rust-O-leum.

Although hard to find around here, my favorite spray can paint is Plastikote.

They changed their formula several years ago and it made it impossible to layer colors without getting a crackle finish where the two colors overlap. I even talked to their support folks by phone, and there wasn't much to be done besides lay down multiple fog coats and have to sand to a decent finish...I know that sounds like a lot of work for a rattle can paint job but it's hard to justify buying two $45 quarts of automotive quality paint to paint a 3 foot r/c sailboat.

^^^This.

Same thing worked for me with some small brackets and black paint. Wait for SWMBO to be out for awhile, though. It does create a tell tale smell.

It could be a reaction to the original paint if its important to you strip it to bare metal and start over

try finding something other than Rustoleum at HD - NOT.

I have to go to the local hardware store or car parts store to get Krylon.
I did not know until recently that Krylon is owned by Sherwin-Williams.

Rustoleum has a huge presence at the big boxes.

Interestingly Krylon industrial also owns Duplicolor and VHT which are found in the car parts store.
http://www.kpg-industrial.com/
The parent company of Krylon is Sherwin-Williams:

The parent company of Rustoleum is RPG InternationalL

humidity here is 40-50% in the house right now. Last night it was still really tacky like 3 days later. I got out my heat gun and heated it for a few minutes. that seemed to make it worse, but then once it cooled down over night it feel drier this morning. I was wondering about the oven, but my wife wouldn't like that smell too much lol. I may just have to deal with the long dry times on this project and then switch to krylon as you guys are suggesting.

I think to coat the other side I'm going to try heating the surface of the metal with a heat gun to 90-100 degrees, then spray a few thin coats a few minutes apart. That'll probably need to dry for 3-4 days...but somehow knowing that it'll take that long is better than worrying about wtf won't it dry when not expecting to take that long...I guess it's all about managing expectations

I have had some luck with heating small parts in the oven once the paint is sprayed onto them. I've had better luck with preheating the parts a bit (perhaps to 100 - 110F) before painting. Sometimes heating after painting has caused wrinkling.

I'm not a fan of Rustoleum in aerosol cans -- it does take a long time to dry. The only way I'll use Rustoleum is if I can brush it on or spray it out of an HVLP gun. Either way, I add Valspar catalyst. It still takes a while to harden, but eventually it does.
