I must be having a slow day....how does using a fast reducer retain solvents? wont the 870 evap. out quicker at 85 than at 70? or does the say,,,885 keep the base wetter longer to not skin over and let solvents out?
I've just never had a problem,,,spray 870 up to about 85 degrees and use 885 if it was real hot..
get technical,,does it have to do with tail thinners and such?
you think i would have been better off using 885, ?
