i am wanting to roll on truck bed liner on the trim of my truck to prevent rust, and protect it. has anyone tryed this? i helped my brother do it put it was spray on and wasnt a truck. If i do this how much of it will i need?

 

I did the bottom 6 inches right below the little indentation in bedliner (spray) a few years back after doing some rust repair. I wouldn't do roll on in this application, you will be better suited just using spray. Took me like 4 cans I think... You want a good thick coat

 

What spray did you use? I wanted to have mine done in Line-X, but the quotes I got were like $600.

 

do you know how many gallons or quarts you used?

 

I will be doing this exact same task this summer. I will be adding fender flares to cover the rust repair and also Spraying bed liner along the bottom trim.

I Plan on buying spray rather than roll on.
