Review: Great “plastic maker”. - Bought it to repair the windshield pillar on my car. After mixing the product it takes around 20 to 30 minutes to start becoming harder. After an hour it hardens and it has a little rubbery texture. I sanded it and painted it afterwards, great result and easy to use.
