letr's get the record straight on carpet and ACC. i am V.P. of sales, been in carpet business since the 80's. 5 years ago, we had an issue with green dye migrating out of gray carpet. four things can be the cause. high heat during the molding process can cause the green pigment migrate to the surface of the fibers. second can be chlorides in salt or cleaners to bleach out the various blended colors in the dye mix. third is UV sun rays. the fourth can be a poor dye mix that doesn't permiate the yarn during the dye process. this turned out to be the biggest culprit back then. we buy our carpet from dorsett carpet in dalton, ga. we have bought from them for almost 6 years. i am on the front line with customer complaints of any kind. we guarantee our carpets for any quality issue for 12 months. full replacement. have never heard the government involvement story before, that's a first. all our carpet is 100% nylon. UV rays will degrade any nylon carpet, rot it out, bleach it white. i have factory carpet pieces showing this stored in my office. i don't know what the mfg date was on the green carpet, so i'm not able to help on that one. anyone who wants to chat on this can call me through the office @ 8006332358. as for heavy carpet we have a line that is twice the wt of our normal carpet. sadly, it has a dozen colors and none match well with your cars. hope this helps
