Clearing with a high dew point

[sprint_9]

Wondering what steps I should take when clearing in high humidity / dew points. On my blue trucks box I didnt think it was too bad weather wise, but when I did my box it was probably the highest heat and humidity that Ive sprayed in, 85 with a 65 dew point. The result was that it came out fairly dry even though I upped my fluid. Im using slow activator with Universal.

I have some retarder Ive been contemplating on using in all the coats to help combat what I have been seeing. I normally add 1oz in my final coat of clear. Im wondering if I add retarder to all the coats and just stick at the 1oz or do I add more, or not at all?

Im planning on flow coating my box this weekend so Im trying to plan ahead. The forecast, if you can believe it this far out, shows 77 with a 65 dew point, so a little cooler than before but still fairly high humidity.

Our dew points here haven't dropped below 70 in quite a while. Been spraying quite a bit of universal lately in extremely high humidity and 90 degree plus heat. The retarder has been a life saver. The last complete I sprayed using extra slow hardener and 2-3 oz. retarder in every coat was still a little too fast! Being that it is a flow coat it should wet easier the first coat, so maybe just add 1 oz. the second coat and see how it looks. If it still looks drier than you want, go to 3oz. on the third. It will flow, especially in that dry weather

1oz per what? 1 oz per cup full or 1 oz per gallon?
You can use way more retarder than the suggestions you read,
I have used as much retarder as activator (and a little reducer) when it's hot, works great.

1 oz per quart is the size I was referring to.
