I run stock 17.5 at a few local indoor carpet tracks with numerous other T4 owners. We have noticed the underside of the chassis edge will get a build up of carpet/traction/etc "gunk". Of course it easily cleans off in between rounds. Apparently, this is a common trait?

My consern is that this summer I will be running outdoor asphalt and conserned the chassis edges may take a beating. I found there are chassis protector films (mostly for off road) that may help?

I suspect some of you have encountered this running outdoor and just looking for your suggestion.
