I was going to cleanthe pump on my resin can and it was stuck. A thick hard skin developed on the surface and I reallly had to crank on it to get it out. The extension tube is still in there. I tries putting the can in hot water but didn't really help though it may have started to soften. I am using EAST system and was wondering if anyone has any info that may help.I will talk to the guys at Noahs tomorrow but hoping to finish epoxying the hull and deck together today.
