Ok, u spending another 0.50 cent to get this one out of me!
There is a special type of tape, not sure of exact name, but I recall it being called "buddy tape"...it super expensive, but worth the money...at first its hard to work with, because its so stretchy and can be pulled so thin...but its better than paraflim for being stronger and lasting longer in your drawer, without losing its elastic properties.
I don't know where to get the tape though, a friend has been giving it to me, and I have to ask where she gets it.
Parafilm works good to, but I never wrap graft union with parafilm...but with buddy tape, if you are good, you can use to wrap graft union, and seal scion! its truly a nice product.
Let me see if I can find where to get some.
