Does anyone know of a place in the NJ area that does spin-weld fittings on ronco tanks? I have two water tanks from a Catalina 34 that i'd like to add fairly large access ports on. The tanks are very dirty inside from leaking deck fills. I've tried to clean them with various methods, but I'm afraid getting my hand in there is the only way.

i searched around on the web, but i wasn't able to find anyone that specifically said they do it, or i wasn't looking for the right thing. if anyone's had this done in the area, please let me know here. short of that, my only other option is to install a beckson port. which i think i can seal up pretty well using gaskets from mcmaster, but i'd rather have a spin welded port if i can.

thanks
