Blue liner is a very strong tape, but it does breakdown and get gooey . For me, the most I can go with blue liner is about 4 days. After 4 days, the cleanup is a nightmare and can really put a strain on a SFS base. I have had much better success with ST-30 (the best) and Walker No Shine. Once ST30 is back in stock, try it out, it's great. In the meantime, I have been using Walker No Shine and it is a great tape as well. I can get 7-10 days of good hold with Walker no problem. I remove with 91% alcohol and then clean up my scalp with Pure. I then us a magazine slide to clean up the base. I use Base Bond in the front, so I'm not sure now you will like Walker for the front hairline. I seem to remember that you have a high densitiy, so it should not be a problem.
