The owner claims that the paint is original so that should make it a single stage paint.
For polishes we have
menzerna 106ff, 085, the new SIP, ZPC and presta 1500/SMR to choose from. Have black (should not need that one) and Green edge wool. White/yellow CCS, white LC and green P2 pads.
We will start light and work our way up as needed.
I think that is a cig lighter next to the pass seat.
For the interior, 2-3 hours of vac followed by many passes with the mytee. Steam clean all surfaces. The seats will get leatherique.
