I like that tape dispenser, although I would use it for my 2" filament tape and that's because I have no idea how good polypropylene masking tape is.
Me neither, haha. It's supposed to give you really clean lines for painting but I've never used it for painting. The name is actually Fine Line, 3M 218. I've had a 3/4" roll of it in my tool box for yrs. Never occured to me what is was or where I got it from. I use it mainly for protecting the finish of parts when I need. I think it might work for masking when anodizing but haven't tried yet. I wanted a couple of wider sizes then looked it up. That stuff is expensive & I would never pay full price. Luckily I found some 3/4" & 1" rolls on ebay a few months ago. The 2" rolls I just got last week. Those cost $50 a roll & I found 5 rolls for $33 shipped on ebay.
The tape dispenser is nice & cheaper than others on Amazon. Made in Taiwan. Again, we used the same exact brand at my old work but in 2" wide. I used them at work for kapton tape & 3M adhesive transfer tape. The blade is really sharp. The yellow thing flips down which is a cover to protect the blade (or rather you from the blade). I got the 3" wide one with suction cup base & I'm thinking of picking up another one in 2" wide.
Yeah I know, just a tape dispenser that I blabbed too much about but I really like these.
