Well Made Tools!
I have been installing Kilmat in my early 74 Datsun 260Z restoration and these tools are very nice for the price. I like them because they actually have ball bearings and move smoothly over the matting. The size selection is very handy as well and even has some nice finished wooden handles.

Must have
These things a freaking AWESOME!
If you're doing a big sound deadner job, you need thees! The 3 different sizes are perfect for the different shapes in the floor pans. Well built, good quality and they have a nice weight to them. Just buy them and thank me later. For $15.00 you can't go wrong.

Convenient Credit Card
This is an effortless and convenient way to purchase Amazon products. Unfortunately I am on it almost daily so the cash back feature is a plus.

The worst banking experience
Stay away from this card if you want to keep your sanity, they had a welcome offer of $750 that they refused to honor, if you call customer service you will be on hold for 2 hours just for them to transfer the call to someone that doesn't know what they're doing. they still ask you to send them documents by mail or fax to prove you're not lying to them.
I closed their card less than a month after opening it, the worst banking experience of my life.
