FYI, finally got a reply from Al's on the HNR. I bought a gallon from Advance with the coupon and it came with really nothing.....
General: Front Label
Al’s HNR (Heat and Noise Reducer) is an inexpensive way to drastically reduce heat and noise transfer. With our ceramic based coating, heat is reflected keeping your ride cool in the summer and warm in the winter. With the density of the material you will also see a excellent reduction in noise transfer. Al’s HNR is a light weight easy to apply answer to your heat and sound reduction needs! Excellent for cars, trucks, jeeps, RV’s, trailers, even residential and commercial applications. Al’s HNR works great with a top coat of Al’s Liner to provide an amazing noise and heat reduce for interior automotive applications.
Application: Back Label
We recommend applying AL’s HNR at 31mils or 1/32nd of an inch thick. This will provide the heat and noise reduction you need. You can brush, roll or spray apply HNR and as with all of our coatings, if you need more protection just increase the thickness (we never recommend applying more than 62mils or 1/16th of inch). At this recommended thickness you will receive 44 square feet of coverage per gallon.
Prior to use thoroughly mix HNR using paint sticks or drill mixer to insure proper consistency. Clean area to applied with a fast evaporating pre paint cleaner (keep in mind all rust, lose materials and debris must be removed prior to applying HNR or adhesion cannot be guaranteed. For smooth surfaces you will want to light scuff to give a mechanical bond or apply base coat of Direct to Metal or Self Etching Primer for a chemical bond. Always follow the manufacturer recommendations when top coating primers with HNR.
You can apply HNR using the Al’s Texture Gun or Al’s Brush and Roller Kit. When applying with the Al’s Texture gun you will need a minimum of 7CFM and 20 PSI at the gun for proper application.
Immediately follow application clean application tools or any overspray or spillage with soap and water.
