SEM makes a nice grey that covers well, sticks to anything, can be clear coated and is easy to recoat later. Did mine w/ a HLVP gun & it came out well. Stuff also works well for inner fender areas, under the trans tunnel etc. Can be brushed on if the finish isn't so picky. Lighter colors sure make it easier to work in later. Masking will take longer than you think.

I also konw a guy who sent is SM car off to Macco and they did inside & out for about $500. He did all the dissassembly/reassembly. He said they didn't get too many of the gauges painted over.
