Hi all... spent the weekend dyeing my door panels and and painting my interior doors white. I'm a little surprised at how good this stuff works. My front seats need to be replaced as they are ripped. My backseat is in very good shape.... a good dye job would work wonders for it but am not sure how well the dyed back seat will match new front seat upholstery.... also, if it doesn't match well, how likely will it be that I can buy new back seat upholstery that will match the front seat upholstery? Is there a lot of variance in vinyl upholstery lots? I'd like to avoid buying backseat upholsteryat the same time if possible as there are other things in the car I would like to address first... any thoughts?
