So kinda of a weird problem--please look
 

I had the underside of my Z undercoated with rust proof stuff from the dealership in 09 not knowing it would look this bad and collect so much dirt. Is there anything you guys are doing to the underside of your cars to make them look better? Maybe paint the whole thing black except for the transmission.It just looks like a dirty mess and I can't stand that.The stuff is also like rubber and sticky. Any ideas are welcome, thanks

if anyone has pics of what they have done please post

if you don't like that rubbery black undercoating, try and get it all scraped off and do POR15 instead for some rust protection.
