Retarder

[Barry]

You can use more retarder, reducer could speed up.
No real limit as long as you can control and heat will support the evaporation.
I used 25% this morning added to the 4100 clear with very slow activator, four coats with no flash, looks dipped.

As You know my panels hit 100+ all summer. Heat and wind changes everything on an hourly basis.

Thanks Barry.

I was very happy to add this to my inventory, it was 98 in the booth today and the retarder really helps a ton.

Also, is it just me or does the clear buff up even better when the retarder is added. It buffs up incredibly well in the first place but each time I've used the retarder its buffed up even easier.

It may have a play in buffing for up to a week, but depends on a lot of other things also.
Some of what you are seeing may be just because everything flowed out a little more and it all tighter.

For primer it would be used when doing large areas in hot weather, very much needed in SE in summer times.

Clear could be used for same reason but I see it more as a finale flow coat.

Something I did the a while back had a panel the after three coat busted out in solvent pop, here and there, my fault for rushing last coat.
Added, some to clear and sprayed a double coat non stop, not a pop left, now that was a flat surface, so a side panel you would need to be more careful.
It was pretty when done, kind of left me speechless to turn a cluster, into a perfect surface.

How soon after noticing solvent pops did you spray retarded clear? Did it have to be sanded or did it melt in? If it melted in, what is the time window for doing that procedure?

Is this stating that it's not necessary or even preferable to clear back to back with retarder with no flash time for the dipped look?
