WireTrim Edge Cutting Tape, 1/4-Inch X 100 Feet (1 Roll, ProLine S)

I invented the product and I can assure people our quality control is second to none.

Love this, fantastic price

Worked perfect for masking a bedliner. Nice clean cut on removal. Did allow some primer seepage in an area that was primed first though.

Awesome 👌

Best tape on the market for the purpose.

This cut through the high-build undercoating very nicely. I applied it lengthwise along my Jeep right above the rocker panel so that I could coat the rocker panel with black undercoating and have a clean break at the body panels. Just make sure the applied product (Undercoating/bed liner) is nicely dry before removing this wire tape. I made the mistake of starting to remove it before it was dry and I smeared a little. I waited for the rest and it cut a perfect line the remainder of the rocker panel! Cheers! Ps. make sure to have good ventilation when spraying the undercoating so you're not found on the garage floor the next morning.

Good wire cutting tape - best what I have found so far

Do not use with brush or roll on liner. I’ve used it before with spray liner and it worked great, however the roll on liner for whatever reason seeped behind the tape in multiple places and looks terrible. So for spray liner good, roll on bad.
