Ipc boars hair is ok , I have seen the unger boars hair in action and I think the ipc is better . Ipc uses a shorter hair and it’s really stiff . I seen the unger , and the hairs get really tangle up and when wet looks like it has very little hairs .
Now what I don’t like about the ipc is that it’s really heavy and you have to take off the glass to rinse . But I think that’s with every boars hair . Also when scrubbing it scrubs good but it grips on the glass and difficult to move around . But it cleans well. Also , I had to trim the hairs from around the jets , because it would block the flow . I think my next brush will be the tucker hybrid with Steele wool attachment , I just been to busy to order , I will soon thought
