FYI, recent M-L work done on my 80, we sprayed it. Bit rougher texture than seen on the Tundra, at least from what I can tell. Hood holds a lot of dust in the texture, side of truck not as much. Have 2 chips in the M-L in 6 weeks. One in front lower valance from a heavy rock hit, even dented the valance. One in the sill from another rock. No panel damaged but chipped through the M-L. Both I think I can touch up. I drive a gravel road every day (Spring Gulch) and have aggressive tires, kept my flares though.
I think prep is everything with most bed liners. We prepped my truck well before spraying. I got to say I had Line-X in the bed of my Tacoma and liked it more then M-L. But it faded, not sure if they have that resolved these days or not. Also not sure if Line-X is tintable. Also not sure you can get it for home apply. But it is a superior product in my mind. The M-L doesn't seem a ton better than Dupli-color or a few other auto parts tore liners I have used other than it does have a catalyst.
Cheers
