I'd love to get a Speer Winter Tarp but I hate that grey color so I just emailed Ed Speer to see if he would know the answer to this querry.

Anyone try dyeing their tarp with clothing dye, like RIT's dye http://www.ritdye.com/ for a change of color? If so, did it damage it or change it's waterproofing at all? I wonder if a water repellent can be sprayed on after dyeing?
