Been using liquidator channels for a long time so decided to renew my 12" 1.0 channel and get a new 2.0 channel since all my others are 2.0(10"&14"). I'm now onto my 3rd new channel and still getting allsorts of lines bleeding out the channel. All of them between where the handle clamps on and where the end clips start. All 3 channels from 3 different suppliers( wcw, wcc & cleaningspot). Anyone else been having problems with this size
