Just want to ask does anyone spent lots of money on a ABS lip kit and broke it on a speed bump? and how much do you pay for paint job and installation on your lip kit?
In this case you probably failed to mix the two parts completely or the resin developed a hot spot and didn't cure evenly. The more time you can spend mixing the epoxy the better, two part epoxies really need to be completely mixed for the best cure. When epoxy resins cure they generate heat which speeds the curing process, normally this isn't a big problem but in the case of an irregularly shaped mold the resin can generate more heat in thicker areas than thin which can cause an uneven cure.
