Honestly think this thread should be renamed “Liquidator User Issues”. I’ve been using these from day 1 of Liquidator 1 release. When first received attached one to a Moerman handle soaped up a couple of windows and did a few straight pulls until the angle was dialled in. No issues. Wet glass, extra soap, and tight fan ensuring there isn’t too much dry glass at the top of each stroke. Rubber cut absolutely flush with the end clip means the clip acts as a bump warning against the frame and not the rubber. Light touch in hand is really important as is a pedantic attention to retaining the blade to glass angle, especially on the turns.
Straightening the clips is a waste of time. If you can’t get the knack of the slightly ‘springy’ dog ear then rip the clips off and use it as a normal channel. By the by the angle is slightly less on the V2 clips because they are a harder plastic.
If you insist on using soft rubber (many do) then wedge some sort of clip retention (bit of paper clip or zip tie) between clip and rubber and that negates the propensity for it to fold and catch on a sloppy turn.
I personally use Razer Red, Moerman Hard and Black Diamond Hard (although I’d class them all as Medium). I’ve even used Wagtail (definitely hard) with no issues.
Vigorous use and frame knocking with the Excelerator can cause the handle to float slightly and if you are having that issue then put a little bit of stop tape either side of the handle, NOT on channel under handle as it changes the jaw gap and the pivot becomes a little sloppy.
There is no such thing as the perfect tool and if Liquidator / Excelerator doesn’t work for you, no biggie, just go back to ‘tried and true’. I personally wouldn’t use anything else.
