It works perfectly. I see some say it wont stick. It does if you paint the area with a coat of polybrush first like the Stits Instructions state.

Works well but I feel that this product is over priced.

only needed 6 feet

Just what I ordered

I did a 32 foot wingspan with flaps and tank bays, had like 4 foot left over, anymore and you,ll need a second roll of this high dollar stuff.

This is not a Poly Fiber problem, nor is it an issue with A/C Spruce. This is a 3M tape provided through and part listed in an STC. Yet the quality is terrible. I ordered 6 rolls. Costly. About 1/3 of each roll is unusable because 3m cant keep the glue on the tape. It appears the tape must roll in the adhesive process and hence the sticky stuff gets all over. Its a gummy mess and i end up just cutting these areas out. 3M should be held to a higher QC if they are supplying aircraft parts through an stc. Or Poly fiber should find another product.

Adhesive does not cover entire tape,and its coverage, and where the adhesive is located ,seems to vary roll to roll. Cant get a good look under the finishing tapes as a result. Expensive and poor quality control.
