I took the bronco on the SOWEGA run, and drove it all day, mostly less than 20mph. I can say that the noise is drastically reduced. On prior runs, the exhaust would reverberate back into the truck and the drone was almost unbearable. That reverb was cut back and made the ride much more pleasant.
I can also say that the heat was cut back a lot more than I expected. Under the carpet, the top of the peel & seal was hot, but nothing like the bare metal was in the past.
I have to say this is a great, and cheap, upgrade that will make riding around a more pleasant experience.
Installation notes:
1. mark your bolt holes as you go. It is not impossible to locate them afterward, but it will save you time when you go to install your seats/belts.
2. After installing the peel & seal and carpet, then drilling holes for the cage, the drill bits were extremely gummed up with a mix of tar/foil/carpet. I simply left the bits in a cup of mineral spirits and they cleaned up easily after about 30 minutes. I left mine overnight because I was done for the evening, and they came out perfectly clean. I suspect mineral spirits could be used to clean the tub after scraping off the bulk, should it ever need removing.
3. I overlapped all of my pieces, so that 1" layed on top of the last piece. This should give a better seal as it appears to me that peel & seal sticks better to itself than to the substrate. I used a 2" strip in the corners where vertical pieces met the floor, to help ensure the verticle piece would not fall off.
4. Keep in mind when covering the bed, that the ribs will cause the 3' piece to only cover 2.75' of area because of the rib surface area. So don't lay down your 3' piece all at once and expect to work it into the rib. Instead, peel off 2" on the end and work it into the rib as you go and peel back a couple inches at a time.
5. You will want a big roller, I used a piece of 1" pipe, and a small roller, i used a paint roller with the rolling part removed. I also found the back of a plastic screwdriver to be useful in working the peel & seal into the nooks and crannies.
6. When working on a depression, such as on top of the wheel wells, lay out your piece so that it covers the depressions, then cut the foil in the middle of the depression. This will allow you to work the material into the depression more easily, then cover the cut with a small 1" strip. The tar material will stretch easily, but the foil does not.
