I USE PPG STRATO CLEAR ITS HIGH SOLIDS HAS 3 DIFF HARDENERS AND IS OUT OF DUST IN 4TO 8 MIN .THEY DONT SHOW THAT YOU CAN REDUCE IT BUT I THIN IT DOWN WITH DT 860 OR 870 (BEEN DOING THIS FOR YEARS). WORKS FINE OVER HOC BASE COATS.
THE P SHEET FOR CONCEPT 2021 SHOWS DUST FREE TIMES AS HIGH AS 70 MIN AND AS LOW AS 10 MIN USING DFX11.
