Well I used under my hood about 3 months ago. Looked really good still. One thing I did notice.....no accumulated dust and dirt like silicone would. I'm very happy with AA foam.
To me, the waffle hold the product better and have more bite than the flat pad of the same color. They do stay cooler but it's not a big deal with the PC. I can't wait to use them on my rotary though!
Thanks for the compliments guys! You all are great!
