Another consideration on the Swain coating that I refer to as rough sandpaper and Swain calls textured. The off white coating might be challenging to clean from greasy/dirty hands, road tar, other road hazards that would mark up the side pipes. By the additional application of a coating with the high temp baked on black, the nooks and crannies, i.e., textured/rough sandpaper, were filled in and the appearance became more like fine to very fine sandpaper. I did visit Swain in upstate NY prior to using them and viewed their process. The ceramic particles are visible and the result is the " textured " appearance. A guess is on other applications the ceramic becomes a liquid and mixed in for attaining the smooth and colored look.

Not implying that the Swain coating is best or better than others, just would be helpful for all when making a decision on a coating that the term " ceramic ' as used with exhaust coatings was clearly defined by the vendors in order to make a valid comparison. Some sites mention ceramic, but no details such as thickness etc
