No Longer Here, BY CHOICE
I use the 3/4" black pipe. I think its pipe for gas lines. I bought mine in the lengths I wanted, allready threaded. I wiped down the pipes with mineral spirits to remove any oils and covered the top of the pipes with packaging tape. I havnt had any issues with black marks and it also keeps glue from sticing to the pipes. The movable clamp end will marr the tape up over time and it will need replaced but thats no big deal.
