I bought a 2004 ZR about 3 months ago with the burnt orange ventilated seats. The driver seat was heavily cracked and the left seat back bolster had some tearing. Looked horrible.
I wanted to re upholster them but did some researching and decided to go with Leatherique products. End result are my seats look like new. To color match I used MSPaint and did 2 solid days of printouts to get a perfect match. The owner of Leatherique now has the color in his database.
I followed Leatherique's instructions to a tee. I did use his clear top coat but was unhappy with the look (way too shiny), so I went do Michaels and bought some satin clear coat water based acrylic and put that over the top coat. Worked perfectly.
The crack repair and re dye is holding up great.
Lots of information but the website is very dated and pita to sort through. Well worth the trouble though.
