The same for the rockers. Just make sure you get them scuffed up good. The pros sand the paint with like 220 grit or even 180 grit paper. That is way too rough to do a traditional paint job which would be like 500 grit or finer but the bed liner will cover those rougher scratches up easily. If you can get access to a compressor and a D.A. sander that would be the way to do it.
