good attempt 👏. a few things to help ya the roller brush on method isnt the best need spray bedliner on to have it look uniform and even. i would look into raptor liner. 145 for the kit and 30 for the spray gun at autozone or Amazon. looks awesome when done have done a few beds fender flares and whatnot with it always turns out great and even. u can use it to spray over what u already did. i guarantee you will be 100% happer with it.
I may re-do it with spray later! I just didn't want to mask everything and get an air compressor to do the job but it definitely would have turned out cleaner! Thanks for watching!
