How is it done?

 

I'm not sure but I think a little "Tilex" might clean that right up....also works on mildew and soap scum...

 

You *****...not that kind of molding.... like molding it to a plastic panel or bose kickers lol.

 

They use a spray adhesive made by 3M sold at most large auto parts
stores. Used it on replacing the kick panel carpeting and went on very well
and holds great.

 

i concur. ^ ^

 

It depends on the kind of carpet. If covering with an unbacked carpet like you get for speaker boxes, it's basically a matter of having a good adhesive and knowing how to stretch & form the carpet.

If it's a heavier backed carpet like what you'd buy in bulk to go along with your new automotive carpet, it's more difficult because it's more rigid. That carpet is bound in a plastic backer that needs to be heated in order to become flexible. You don't have nearly the same flexibility with this as with the speaker box carpet, but with some carpet colors you can't get a good match from the box carpet.
