Any suggestions on good caps (fiberglass) and bedliners (sprayed in vs plastic)?

 

without a doubt, sprayed in is the way to go on bedliners. they will outlast any drop in and aren't slick so your cargo wont slide around. also, since there is no space between the bed and the liner, there is no chance of trapped water/moisture causing rust.

 

I went with the grey Line-X spray-in and a Leer topper... Both have served well...

You can see both in my "Big Red" gallery to the left <--

SnugTop, I had Leer, and Inovation in the past...

Bed rug, the best hands down
