I know this topic has probably been discussed in the past, but I'm curious what experience anyone has had with the 3M product. It appears Andrew has had good luck with it. However, I'd appreciate some additional help before I make a reasonable investment in it in both time & $.

Does it really work?

Any experience with "do it yourself" installation?

Is it visible once applied?

Does it last?

Who should I buy it from? I live in Ohio.

Any feedback on cost of professional installation would also be helpful.

Thanks for your responses!

Judy
