It didn't work on my son's Wrangler plastic radiator at first - after 3 hours it still wasn't cured. Since it's epoxy, I thought the extra heat might help, so every 10 minutes or so I'd go to the garage and heat the patch up with hair dye on high. It took another hour +/- but by then he was fully healed. It was enough for a 6 mile drive to the cooler shop where we bought a new cooler so it did what I needed.
