There are more than a few companys that make vinyl/plastic paint specifically for this job. They have all of the GM colors available. Your interior color code is in your glove box. SEM makes a great product. If you want an easier route, Duplicolor vinyl/fabric spray has a couple tan colors that match good too. This can be found at pep boys, etc. There is no need to have a color mixed special because companys like SEM, etc., have the exact colors/codes already in a can. If you google GM plastic paint you will have your pick of brands to buy, all coded to your exact color.
