joberg have you tried baby oil on rubber that you spray painted?
Spray paint failure... Painting over rubber forever tacky

I tried on EVA foam. I had the same problem as you; the paint was forever tacky. I had sprayed my piece on a very humid/hot day (my fault) and the result wasn't good at all. I tried the baby oil trick and it worked. You dip your finger in the oil and dab it on your painted piece until every inch is covered. Don't use a paint brush or a rag; the fabric tend to stick to the piece and the paint brush is no better either.
Good luck.

On two different areas of tacky paint on flexible synthetic material (not certain what kind—maybe vinyl)…
Applied mineral oil (aka baby oil). No affect. Removed oil with isopropyl alcohol. Still as tacky as ever.
Sprayed 2 thin coats of Krylon Triple-Thick Crystal Clear Glaze. Worked like a charm! (Applied 2nd coat a few minutes after 1st coat, when 1st coat seemed to be helping.) Tackiness disappeared within minutes. I’ll wait another 24 hours, then retest, but I think my problem is solved. Yay!

If that is a long-term fix I’m super excited! I actually went back to the model/toy that I had trouble with and spent a whole day basically using a toothbrush and alcohol to remove all of the paint and started from scratch, but if I could just use Krylon glaze to fit it that would be a thousand times quicker!

It might change the underlying color. I used Krylon only because that’s what I had on hand. Rust-Oleum also makes it. I’ve used both. Noticed no difference between them.
After 48hrs, I’m going to try covering with the original paint. The one that stayed tacky. Hoping the clear sealed away the cause. I’m using a highly reflective metallic paint, which cannot be clear coated. Such paints aren’t very durable, but they sure are pretty!

After 24 hours, the tackiness began to return. After 48 hours, almost back to full tackiness.
OH WELL!

BTW, in the past, I had the same problem, but with sprayed-on Flex Seal. The only thing I found that worked was to coat over it with something other than spray paint. In my case, Gorilla Clear Crystal Waterproof Patch & Seal worked. Using just a plain old brush.
Perhaps coating with a clear spray intended for vinyl might work. Who knows? But I’m no longer interested in experimenting. Ugh!

I definitely think this needs to be broken down to base compound. Rubber, vinyl, plasticized leather, etc.. I recently did a vinyl project. Tacky forever. Crystal clear solved it outright. I think the rubber issues are similar but not the same and need their own set of tests. I know that I personally don't like "too late, you should have" but primer and or the correct paint is always the go to and using the right paint got me a one coat complete finish on a second section. My project had only a thin layer of vinyl on cloth so possibly it is a chemical balance by volume issue and a couple coats was good on mine but not good enough for a vinyl all the way to the core object?? I just think that true rubber vs vinyl is not even somewhat close chemically so they likely do not have the same resolution.

Throw it in your freezer! I do this often, it works. After a few hours (4 or so) let it sit out in a cool spot. It may still seem tacky once it starts to defrost, but as the condensation evaporates. So does the other crap! Once in a blue moon I spray rubbing alcohol on it quick then rinse cold water again, and voila. Never fails!

Wait for it!!!!! Peanut butter!!! Woohoo sticky gone! Now you can paint no problem . Most problems of paint come from poor preparation. At least that’s my problem every time!

Peanut Butter! Then you can paint over with any paint you want! It’s not the rubber! It’s poor preparation !

Could you explain the process of applying PB on your part to prepare it for painting?
I know that I use Olive oil to clean spray paint off my hands. It is an obvious solvent to this paint type and works extremely well. Can't wrap my brain around why it would cure the paint but sure willing to test it on a non important sample. More info? or even just some step by step that you use, like amount/time and such.
