when i changed my awesome Burgandy interior (i never understood blue or red interiors) to black, i didnt have a problem with anything except the door panels. everything else took color great except for them.
i tried SEM, VHT, Duplicolor, all the various sticking compounds, hell i even washed the panels down with soap and water, denatured alky, and laquer thinner. the only thing that stuck was the Krylon Infusion. now my sons S10 door panels, the Duplicolor worked great.
