Resin aint nothin compared to Zep indusrial orange gel degreaser. We use it to clean asphalt off of parts. If left on the skin for any length of time it burns worse than a leaking Zippo in your pocket. One evening I had a 4 inch pressurized hose blow and cover me head to toe with warm AC. On the way home I grabbed a bottle of this degreaser and jumped straight in the shower knowing that this was the only thing besides diesel that was going to cut the stuff I was covered with. Within minutes I relaized just how bad I F'ed up. Id honestly rather roll naked in hot coals than cover myself with that orange stuff again.
