A BUYER BEWARE CAUTION.
I made a greedy rookie mistake thinking I found a good deal for lead tape at the eBay link listed below.
In my opinion the tape at this link is paper thin and mostly useless for swing weight adjustment.
Also, trying to apply two or more layers won’t work because the adhesive does not bond well enough.
I don’t know the minimum thickness needed for useful lead tape, but if the seller does not list the thickness, proceed with caution!
Hope this might prevent some useless grief.
