Wipe off the surface that you will be applying the FatMat Rattle Trap to with a cleaner that will not leave a residue. Be sure to get off all dirt and grease so that your FatMat bonds tightly. This step will make a big difference in how permanent your application of FatMat is. Be sure that surface is completely dry before applying FatMat
If necessary cut your FatMat to the needed size and shape with a utility knife then remove the backing from your FatMat and apply to the surface that you have just cleaned.
Make sure that you use the roller provided, this will ensure a tight bond between the FatMat and the surface. (Your fingers cannot do the job properly!!!). By using the roller you will be able to get the FatMat to stick securely to the different contours. You may find it necessary to cut the FatMat during application so that it lays flat on the surface. It is best to not leave any air between the surface and the FatMat.
