scottboy1973 0 Posted July 5, 2009 Most of my experience has been with 641. Recently I decided to upgrade my white to 651. Since then I have had troubles weeding areas of a graphic that small areas are left. It acts as if the adhesive isn't strong enough or the backing paper is releasing the vinyl to easily. I have tried other colors of 651 and didn't notice it that much. Anyone else have this type of problem? Thanks in advance for your help. Share this post Link to post Share on other sites
Rodger 527 Posted July 5, 2009 I have a white roll . a black roll & a red roll of 651 that are 2 years old . They all seem the same to weed & are as good as when new . Share this post Link to post Share on other sites
tlzimmerman 11 Posted July 5, 2009 in my experience white requires just a little more force or blade depth than the other colors.....seems like its thicker in an attempt to be more opaque, maybe you aren't geting it cut all the way through. Share this post Link to post Share on other sites
Guest sciondrgn Posted July 5, 2009 I use 651 for everything, No problems here and I dont change any settings.. The backing on white is different, maybe thats why you are noticing a difference Share this post Link to post Share on other sites
