Amazon sells the Dicor butyl tape. It's fine, but not as sticky as some others. I can't point to a good name, I usually just go to the RV dealer and examine what they have on the shelf, if it's stretchy (taffy stretchy, not rubber band stretchy) and sticky, it's good. A roll lasts a long time unless you're doing everything. Butyl tape will have a smooth surface coming off the roll, putty tape is usually rougher.
