Not a fan of Meg's UP on interiors, too shiny for my taste. If you want something OTC and in the Meg's family, Meg's natural shine is a good product. My favorite though would be Ultima Interior Guard Plus.
if you can, pick up some of the 4" pads and a 3.5" backing plate. I just did my first correction on my car on Friday and the smaller pads were perfect for getting the pillars, bumper, and the tight places on the trunk.
post some pics when she's all done.
