Single Stage Urethane

3 coats sanded flat and buffed could be nearly half gone by the time you're done, not to mention future detailing. So it's best practice to start with enough film build to ensure good service life.

I really don't see the need to mix clear with last coats on ss, especially when cut and buffed, except to complicate spot repairs. Spi ss presents as deep a color (black is my experience) as any b/c, possibly more depth. Is extra clear for uv protection? I don't think it needs it.

More curious then anything...

So is there a recommended film thickness to shoot for if you plan on doing a cut and buff?

Enough not to....
Think Universal Clear....
Unless you have a mill Guage which who does . Maybe ask the other Mike and borrow his.

Yes, but I can't give you specifics. I work by the seat of my pants mostly, like if the job is going to be sanded extensively it gets a flow coat, period.

3 coats is the absolute minimum. 4-5 in one application is better, just have to block out the urethane wave. Three, sand, then three more (flow coat) is ideal because you don't have to worry about the urethane wave that you get when spraying 4 coats or more.
