I have read about guys who have over reduced their clear on the last coat. How is this done, do you add some extra actvator or give it a shot of reducer.

Reducer. Keep your activator the same.

flow coat. in my hobbyist opinion i just reduce on cold days. warm days it seems to shoot thinner anyway...

The warmer it gets the more I reduce it, to slow it down.
I once reduced Universal Clear 30% (by mistake) I cleared a bumper
and it came out great, and stayed that way to my surprise.
And it was slick!!!!
Usually, when it's real hot, above 90, I reduce it 20%
75 and below I usually don't reduce it, cooltemps really slow it down.

I personally never reduce universal on overall jobs. I use very slow activator...even in a down draft at 100 degrees the very slow act. slows it down enough even on the big jobs. 10%-20% reduction would not hurt though. Sometimes when doing bumpers and hoods off the car I'll reduce it down so it will flow a little.
I'm used to how it sprays without reduction, so if I tried doing it on an overall I'm sure I'd have waterfalls all over the place!

Make sure you use a quality reducer with good tail solvents or you'll have contraction problems when over reducing-this can show up months later. SPI reducer rocks!
Contraction will show as a very fine leathery texture in the surface of the clear long after the cut and buff is done, minor cases- some people will never notice it. Slow is best when it comes to over reduction.

Can this happen in the short term also? I prefer the SPI reducer but sometimes have to buy locally cause I need it now! I have noticed on certain jobs what looks like micro die back...but sounds more like what your describing...and it doesn't seem to be noticeable in the sun light and even in the shade. Noticed it on jobs I have done in my garage in artificial light but seems to be unnoticeable in natural light. What else can cause this?
