hi,

you will have to give people some time as not everyone is on here everyday, as you only left a day inbetween your 2 comments, i would suggest you leave it a week. you may also find that people have looked but dont have any specfic info or help or simply cannot add to anything there type rubbish <<< see last few lines lol

ok so to answer the question, afaik there is no issue with tearing that kapton tape, i have not done it myself but cant see it being a major issue. also that white fluffy cotton wool like stuff anit gonna stay white for long, it will eventually go black after lots of uses, if you are worried you can buy kapton tape on ebay, amazon where ever just google "kapton tape" that will surely bring up some retailers, then just patch it up (dont remove whats there, just add to it).

im sure if my advice is wrong, Geoff or curious aardvark will be along to add to this, there are the geniuses when it comes to makerbots and there clones.
