Minimum time between spraying MP170 and MTK

Also can I use very slow hardner (MH169)and slow reducer(MR187) for 70-80 degrees outside temp?

Or should they both be slow?
Thanks,

I haven't used that combination but I don't think you would have a problem with the mix. I have some of the MH169 but can't say that I have ever used any of it, so I don't know how it works at cooler temps. I'll agree with CNKS and say that I think the reducer selection is a little more important since that determines how much evaporates between leaving the gun and hitting the surface. A slower-than-normal reducer is slower in evaporating and will leave more remaining in the film after application. The result is great flowout but also a greater tendency to run.

I think you'll be OK, especially if you are in the upper 70s. The ranges I provided previously are my own, rather arbitrary ones since I was unsuccessful in getting PPG to define 'em. The rules are not hard and fast and there can be considerable overlap. It depends a lot on technique as to how slow an additive you can handle w/o getting runs. You are a little on the hot side, I think, so don't pile it on, don't linger and try to keep a uniform gun-to-surface distance. At least if you get a run, it's fairly easy to correct with the MTK.
