I'm wanting a "spray in" style bed liner in my truck, but I don't want to pay for a Rhino or Line-X. I'm looking at doing it myself, and would like some feedback from somebody that has done their own. From what I'm seeing on Amazon reviews, Herculiner seems to be preferred over Duplicolor's Bedarmor. I'm also seeing that the prep work is highly important, and that it works out much better if you do it on a hot, dry day. What system have you used? Any tips on doing it quicker or better?
