Spray painted the carpet. Yes spray paint. It was heavily damaged by a 2 1/2 gallon container of pool chlorine (twice as strong as bleach) that toppled over and the lid popped off on because person in front of me HAD to stop for a just turned yellow light. Aaaarrgh!
Anyway, used the duplicolor HPV109 medium gray vinyl/fabric paint. It’s close enough for me. Looks way better than huge bright yellow stains splattered between the seats etc.
And I have replaced the bungee that broke that normally secures the chlorine !
