Euro 5000 - Blending activators, reducers, and flash times

Temps in the shop are 65-68F and I'll be spraying Euro Clear on an overall ('69 Camaro). I have 1QT of medium activator and 1 QT of slow activator. Is it okay to mix activators lets say 50/50 or would it be better to spray the first coats using medium and then switch over to slow in the event that I need to open a second gallon of clear? I have the same question about reducers since I think I'll need to use what I have left of both slow and very slow to get the job done. Yeah, I didn't prepare very well for cooler temps, but I always like to use the slowest activator/reducer I can get away with. I even use a little retarder at 65-70F :eek:.

In terms of flash times is 30 minutes (per tds) still ok or should I let each coat flash longer? (4:1:1.25, 1 oz retarder per sprayable quart, 5 coats, 65-68F)

As always, thanks for any guidance!
 
Rule of thumb, I have always started faster towards the slower end of any product. Just don't start slow over faster. A little extra flash up to 45 minutes in cool weather using slow activator/reducer, won't hurt.

Flash until clear isn't stringy on masking tape.
 
With the Euro I believe the reducer speed has more effect on flow and setup than the hardener speed. At those temperatures I would use medium reducer. I only get the slow hardener so can’t comment how the medium would work. I agree slow as possible but if you don’t have temperature working for you it has to be adjusted.
A temperature gun is very helpful.

30 minutes even in cooler weather is about the maximum that you want to let clear flash off. Any longer and you are risking it cooking up when applying your next coat. As for your question, I think texting Barry on the Techline would be a good idea. He will know better than any of us. I think you could blend it, but I can't say with certainty that you can. I wouldn't blend the slow and very slow reducer if it's going to be cool when you paint. The very slow would require a lot of time to flash in cool weather and you are risking dieback by doing so. Personally I would get enough slow activator and slow reducer to do the job, trying to keep the temps at around a minimum of 68 degrees.
