I have been using 3M Finesse-It II for over 30 years.
Admittedly it's always been pricey but I'm seeing 60-75.00 a quart? Last I remember it was ~ 28 - 32.00.
So, being a tight as-, I'm wondering if there's a good alternative or possibly even better one that's a bit easier on the shorts LOL
FYI: I usually wet sand down to 1500 -2500 before polishing, and kkind of bounce back and forth between foam and the fine wool

TIA
