Thats better done with single stage paints. Not sure about base/ clear systems. Ask your paint store.

I actually did it by accident when I painted my satellite last week. I grabbed a gallon of clear instead of reducer when doing the trunk and engine bay  It was dupont nason which requires an activator. So it cured just fine, but the coverage was terrible. I ended up spraying it over again. I have tried it before intentionally as a way to touch up spots, doesn't work well with metallics, it just shows the metal more than the color itself. Works great mixed with single stage, not good with base coat.

Exactly, I paint work trucks with single stage urethane. For the third coat I mix clear in with my color and it gives it more shine and depth, looks just like base clear and matched the factory base clear white that I lay the companies color over, some of the factory white get's used in the paint scheme. I have painted 2 new work trucks this fall and have a 3rd to do just as soon as we take delivery.

ppg certified painter.
when mixing base coat with clear coat several things can happen.
it can slow down your full cure of the clear.
it can reduce the durability of the clear coat.
the base coat might react with the clear coats catalyst, causing problems on how it lays down. and also how it bonds to the base coat long term, causing possible delamination problems. also it could cause the paint to gel in your spray gun, DBU especially.
you will reduce the clear coats ability to protect from UV light.
with all that said.
ppg approves mixing some types base coats, DBC, with clears catalyzed with DCX61, in JAMBS ONLY, areas that sunlight won't hit it often, but NEVER on the surfaces hit by light.
on the outside of the car only mix single stage paint with clear coat. only mix colors with clear if they use the same catalyst.

There are some factory paints that require a tinted clear to get to the proper color, but I have no clue as to what they use to tint it.
they use another step of base coat with extremely transparent color.
that's where the clear basecoat binder comes in play. don't know much on PPG other then they push the water alot now.

The only time we mix the base and clear is to touch up chips and such on the car with the left overs from painting a panel.
We usually have a quart of single stage mixed when we have the base mixed and use the single stage under the hood, in the jambs and in the trunk area. It is less trouble, looks good and is easier to touch up when scratches and such happen later.
Master, again and still

The Duplicolor product is lacquer. You should be able to mix it however you want. Since it's not catalyzed and only air dries, it can be touched up or repainted any time and has no recoat window. It's not a true basecoat, the product is a ready-to-spray final finish. The clearcoat they offer is optional to enhance gloss and add wet sand and polish capability, presumably for the metallic colors you wouldn't normally cut and buff. I say try it on a test panel before doing it on a full vehicle. I don't see how it could cause any harm in this paint system. From the website: Quote:
Dupli-Color® Paint Shop™ Finish System gives you everything you need to create a high-quality DIY finish - primer, color and clear. Paint Shop is a high-quality lacquer system designed for automotive and motorcycle applications that is easy to apply, dries quickly and can be buffed to a brilliant smooth finish. Paint Shop is a ready-to-spray system that requires no mixing or reducing, and with no re-coat window, additional coats can be applied at anytime.

Maybe mixing base with clear was not was not technically what I heard about. 
Can you tint or do anything to a clearcoat to take some of the appearance depth out of it??

when i spray a high end single stage paint jobs. i put down 2 coats of the straight color. then 3 coats of the single stage color mixed 40% color 60% clear. when i mix this both parts are mixed according to directions. single stage color, DCC, uses more catalyst than the clear, DCU 2021.
you can use almost any tint in in the clear coat. you start having problems when you have to add the binders used in the base coat.
i haven't mixed my own paint in over 20 years so things might have changed. but basically with base coats and single stage paints you use the same tints. you add base coat binders to make base coat color, with ppg there are a few base coat only tints and a few single stage only tints also.
CHECK THE TECH SHEETS of the product or the person mixing the paint to tell you exactly what you can and cannot do with it. every manufacturer has different things you can and cannot do with there products.
