My whole system was treated with 1260 and really enjoyed it. I am slowly changing to the Q45t. Right now i am about at 55% with Q45t in the system and 45% with the 1260. They do work well together (not on the same end of wire). The 1260 wipes off fairly easy with a soft cloth. I only had one connection where it was hard to get off. The 1260 does need to be reapplied several times if you are moving things in and out on a regular basis. Unplug something once or twice and repluge it did not effect the sound for me. Doing it more than that and i would reapply 1260. I have not tried it yet, but i am sure the Q45t should be about the same. The longer you leave it in placed the better the sound.
Good luck
