Answer 1

This is special cloth available in few colors mostly black, not available in open cloth market. You can get it at electronic spare parts whole-seller's shop or speaker manufacturer's shops only.

Answer 2

yes you can find it in your closset  i been using old t-shirts

for years never a problem try and you will see

Answer 3

The cloth that we use on all our fiberglass enclosures is a lightweight polyester fleece.  It is best if it is fairly thin because if it is too thick it will really soak up the resin.  This is only bad because resin is not cheap ;-)  

This is the material used only to shape the enclosure.  It will not really for support at all.  Once you have the fleece fiberglassed you will want to do a lot of fiberglass mat work.  That will be were you get the strength.

Polyester is the best material of fleece to use.  Anything with cotton will stretch once you put the resin on it which will seriously deform your shape.

Good Luck!!!

Edit:  I forgot to add that this material is found at almost all fabric stores.  I have even heard of stores like walmart having it.
