Sorry getting back to you so late. The process for both were pretty much the same (via a PC)- cut with ssr3 and cutting pad, polish with ssr 2.5 polishing pad then EX-P on the ES 300. On the S430 I went one more step with ssr 1 and a polishing pad then EX-P.
Thanks for the positive remarks guy's. As far as ssr 2.5 goes, I often use it with a polishing pad then staight to lsp. I wouldn't do this on black, although you could but most other colors it's no problem.
