I've been thru this.
My Viper came from Houston Tx where the roads are nice and flat. It was slammed as low as possible. Scraping on crap SoCal roads made me crazy! Thanks to the KW ACR Coil Overs, raised it up to avoid the scraping. Adding insult to injury, the guys at the Busted Knuckle Club (where I was DIY'ing the maintenance) were required to put it on the lift. Their lift arms also added some scratches to the bottoms of the rocker panels.
I fixed the scrapes and scratches the best I could (minor filling & sanding) with this stuff from
https://www.automotivetouchup.com/ Got a great VVO color match. 3 coats base color and 1 coat gloss clear. Check the color code for your car. Either GK3 or PK3 (according to their website). I only treated the area of the rocker panels under the car. While I was at it, also recoated the exhaust tip portals. I'm plenty happy with the results.

No more problems since raising the coil overs and getting my QuickJack!
