Does it all evaporate out? Say if i add 10oz, how much remains?
Wondering for shrinkage reasons. Thanks.
10oz added to what and how much of a mix are you thinking? Also what air and surface temperature? Not trying to be a smartass, just thinking the more knowledgeable users need more info.

And I’m kinda surprised to be reading about retarder this time of the year when most shops are reaching for the Polar Accelerator lol

Just using 10oz as a round number for ease of percent evap.
I'm spraying my 91 caddy trunk lid. After base & first coat of clear, i'm wanting to try a one & done flood coat.
It's tarped good, let the drips fall where they may. Reduce psi & soak it like water bottle. No cloud of overspray.
I always cut & buff, perfected sanding runs how i spray lol.

I have done this with straight Euro clear- no reducer. Just a slow methodical application and very wet. This was the result:

I also tried the retarder method. Two coats of clear and then a third with 30% retarder added. This was the result:

In the first picture you can see a hint of what I believe is urethane wave from the heavy application. In the second picture the reflection of the ceiling light indicates a fairly flat surface.

Yes. I believe that is what Barry posted that most shops using the retarder are doing.
You don't have to hose it on, just get a nice even coat so it can melt into the coats below.

So that day was 70F & used 4004 activator which = retarder without adding any.
Plan was shoot 1st coat of clear with base added as i did whole car to restore color & blend which works, but i got a few heavy runs so i had to stop & put it out in the pasture till i can block dark runs.
After they finish shrinking i'll hard block everything & put my final straight clear flood coat & block it. Did whole car this way. People bug out at grocery store especially when i say i did it & from wheelchair.
Had dent when i got it 15yrs ago. Had to finish cause everyone stares at car. GM black sapphire.
Spray with almost no fan pattern cause i can't reach & hold gun straight, that's why i like clear to stay wet long. Works if ya good at sanding heh.
