Back in December I bought an Acura MDX for my daily driver in winter and bad weather.
I started browsing the internet for accessories and found the ebay store below.
They sell "pillar covers" for many makes of vehicles.
These are high quality Polycarbonate covers to apply to the pillars between the front and back doors on several vehicles.
They enhance the appearance of the weathered surface and can be applied with ease.
They come with a durable adhesive tape already on the back so it's a simple peel and stick application.
Check out their ebay store and see if they have a pillar cover for any of your other vehicles at home.
I have attached a photo of my MDX with the gloss black pillar covers installed.
