How do you DYE KICK PANELS?

I changed the interior of my 68 Barracuda from blue (front seat from white) to black with SEM vinyl dye (available at Eastwoods or your local body supply). On the plastic parts I used the plastic prep and on the soft vinyl I used the vinyl prep. Cleaned the parts several times with an ammonia based cleaner and used the prep materials.

The door panels, visors, kick panels, dash pad, etc haven't been touched in the 4 1/2 years since they were done. The seats require touch up once or twice per year where your butt slides over the piping.

I tried Dupli-Color but it didn't look as natural (to much gloss) as the SEM product.
