Back when I sprayed nothing but single stage,....acrylic enamels, synthetic enamels, and polyurethane enamels,... there was no really reliable way to blend them because you couldn't buff the blend area because those paints remained too soft and would basically burn or melt if you tried. Same thing went for trying to wet sand and buff any dirt or a run out of the paint. In a nut shell, how you sprayed it is how it stayed,.....so you had to be good at what you did or you'd be out of a job. Learning on such user "unfriendly" products made using todays stuff a piece of cake. Now that single stage is made from the same type of paint today's clears are made from,... urethane,....the blending is a bit easier. I wet sand the intended blend area with 1500 grit paper, go further out with each coat of color, so where the paint ends in that blend area is just one coat so you only have limited overspray there. Once it tacks up, I come back with the same color mix but reduced almost 100% with a fast drying reducer and I, with low pressure, ( it will atomize just fine because of the low viscosity of the product now that you reduced it so much),...and mist the mix onto the blend area to melt in the overspray and paint edge. Don't extend onto non-sanded paint. Keep this operation in the sanded area. Lightly buff the area the next day.

Bull if you put hardner I your paint wait a day you can wet sand and buff or just buff without any problems been doing it for years now it's a different story if you don't use hardner

I have an opportunity to do some repair work on a fleet of Mercedes sprinter vans. They have a single stage paint with lots of rust bubbles forming. There was another company that did one and the repair stands out very obviously. I haven't painted anything single stage but I'm assuming it's difficult at best to blend base/clear into a single stage panel. Any advice here?

That's bull if you put hardener in your paint, you can wet sand and buff. The next day. Been doing it for years now. If you don't use hardware, it's a different story.
