[Shop-talk] Long board sand paper

[Robert Nogueirao]

Looking to buy a roll of long board self sticking sand paper for body work. Found several sources with a range of prices. Ive always used 3M in the past.Since blocking a car requires a lot of paper I’m wondering if using 3M ( most expensive) is worth the extra cost?
Thanks
