well i just got done with mine yesterday (put the second coat on today) and i must say that spray on bedliner surprised me, it worked very well...but we just used it as a primer for the herculiner but basically the process went: sand down with sander, hand sand, spray on sandable primer x2, spray on bedliner, dry...roll on herculiner...dry....dry...bolt on bumper w/ lights and shackles...and finished second coat a few minutes ago...here's some pics



right after the first coat, used 2 ratchet straps to hold it up, and a bungee in front...on a basketball goal hahah



front view right after second coat this morning



side view, makin the jk look a little too stock haha

and i seem to have misplaced my pics of the first coat with the lights and shackles on it...i'll post those later

PS-the herculiner is VERY thick, but my friend suggested duplicolors roll on bedliner for a much thinner texture, where as the spray on was almost a sandy finish

 

Looks good!

 

haha it looks 100 times better...but here is a finished pic


and this is what you start out with (after hours of sanding haha)

 

Nice info. Thx!
