I've been using the same old mixing ratio for clear coat for 8 years, but a run on a black Honda Civic last week made me grab the tech sheet.

The sheet said 4:1:1, not the 4:1 I'd been doing, and adding that extra part of reducer was the difference between a perfect flow and a sag every time.

What if your old ratio was fine and the run was just bad luck?

Track it for a month, then decide.

A month of data beats a single bad run.

Honestly, that's such a good point. I feel like we all jump to change things after one rough patch. Giving it a full month to see the real pattern is way smarter.
