First thing I learned many, many years ago, for every coat of clear lacquer, allow 10 days min to harden since you most likely do not have a room to keep the temp slightly higher and constant. Even some 2K clear needs this.
The second, was how FAST the buffing wheel rotates. Any more than 800 RPM is too fast. 600 RPM is optimal with a 12"diameter buffing wheel
Third, never allow excessive heat to build up in or on the surface while buffing. Do not press it to the wheel, let the wheel do the work and pull away often.
Forth, as suggested as well by @Bizman62, use incremental polishes.
Fifth, always use a clean buffing wheel to start a NEW polish and grit.
Just my hard earned 0.02 cents worth!!!!!
