Can't Get Rustoleum Paint to Dry / Harden...

It's been about 2 months since I put down the primer, and 1 month since the coat of white+clear hit it, and the paint is still soft . I used the chip resistance professional enamel paint, with recommended primer, and enamel clear coat. Everything is perfectly dry, but if I wrap a tie wrap around the paint surface, it will leave an indentation after a couple of days.

Is this just the nature of a 'rattle can' job?

Sounds normal to me, especially with all the film build you describe.

You want to let it dry more between coats. And don't spray them down so thick, just barely enough so that you have a smooth finish. Enamel also "rolls out" and flows and gets smoother for a long time after you spray before it dries, something like 15-20 minutes. So spray a barely thick enough layer to be smooth and it flattens out and gets glossy right before it dries. Spray no more than 3-4 layers and wait about 2-3 hours between coats.

At this point, you have no option but to strip and re-paint. Use much better high-quality 2-part epoxy paints from automotive suppliers. Ends up costing less than rattle-can paint once you get over 1-quart.

I agree on the use of a 2-part automotive product. Produces much better results. Pretty expensive though and requires special equipment to spray.

Regarding waiting between coats, this is not recommended for Rustolium; recoat time is less than one hour. If you want beyond this time with Rustolium, the under coat layers will wrinkle. Sad but true. Best to follow the manufacturers instructions.
