A few weeks ago I finally painted the spare tire tray. I went to a local auto paint store to see what they would recommend.
Used Klean Strip Prep All, Transtar 4613 Black Primer and SEM 39143 Trim Black Paint.
Most of the time was spent in preparation as is usually the case when painting. Masked the area, cleaned the surface and draped the entire car with sheets, so no chance of overspray.
Two light coats of primer and three light coats of paint. The end result turned out as good as I hoped for. Looks so much better !
