I did read that thread and based on it, avoided Plastic-kote and went for the Hammerite.
Just read back - apologies for the apparent smugness, it was intended to be more of a commiseration.
FWIW the tree hugging version of Smoothrite appears to harden after a year or two - don't know whether it's time or (summer) temperature that makes the difference - but if you're going to strip it off, sooner is better than later. It might even come off with cellulose thinners if you catch it in the next few days? I've had problems with compatibility trying to overpaint the stuff...
