Removing the rubber strips is extremely easy, replacing takes a little longer although rubber grease helps. The issue I found was not corrosion on bolt heads but on the actual running boards themselves due to trapped water which eventually penetrates the paint around oversize holes. You have to remove the strips completely after soaking bolt threads with penetrating oil. Only then can you see any incipient corrosion which can be addressed finishing with painting by brush the inside of fixing holes.

It's then a no brainer to replace fixings with stainless including a nylon washer between strips and bodywork. Add silicone grease before replacing rubbers. With a squirt of ACF50 underneath.
