Can I add rustoleum black as well?
Our black bedliner is generally the best option for black, but you can add quality auto paint single part-single stage or most oil-based or solvent based paints. The parts A and B should be combined and mixed for at least 2 minutes as directed before adding any such color additives. We would strongly recommend you test any modified products first before committing to the end result. Also… any such additive will need to actually dry, so they may cause the finished coating to be tacky for some period of time (particularly for the oil based additives).
