I've primed the tractor with JD buff primer sealer.. it recommends waiting 36 hrs before recoat with JD enamels. Curious to see if anyone has tried recoating before the 36 hrs. It's sat over night and I want to recoat without scuffing. This is my first time spraying any JD products.

So you read the application guide ;that is a good thing . So you want to know if any painters were stupid enough to not follow the guide . Probably not. Why would you try to change what has been factory tested as the proper re-coat time ? That is the real question.
No the real question was stated, but thanks. As with many things in autobody/paint work there is often more than one way to skin a cat. I'm in a bit of a time crunch. And I know you don't always have to follow " factory tested proper re-coat times" to a T to get a good looking finish. So as I asked has anyone ever sprayed over JD buff primer before 36 hrs? Dr sportster you obviously haven't so thanks but looking for opinions of people that have.
Jay I have sprayed it before the 36 hour mark and some times the new paint will soften the primer enough it can bubble an peal. I now wait longer than the 36 hour mark just to make sure the primer is good and dry/cured. If you need a faster drying primer than use an more traditional auto primer. They do not cover as well but do dry faster.

I have done it. Sometimes it works and sometimes the paint bubbles. The failure rate was too high for me since you have to strip it to straighten out the mess. Now a days I wait.

Two guys tried and failed one guy did it succesfully . Your call.
The condtions that the paint is drying in makes a huge difference as well though. I live where there is lots of humidity and is very tough to get paint to dry within the recomendations, where as in the winter here with the heat on with dry air takes very little time, and usually get away with quicker dry times than suggested.
Well, I have used it with success many times, and not one time have I waited for 36 hrs.
In fact, if I am in a hurry I will lay down the buff primer on bare steel, wait until its flashed off and maybe dry to the touch then go ahead with 2 coast of green or yellow as the case may be. Have never had a problem. First time I tried it on a homemade bale chute for my NH311 baler.....quick sandblast to rough up the new steel, one coat of primer followed by the paint. That finish held up awesome.....paint and primer were bonded together so that when the bales wore through the paint and primer over time it was like it had been wet sanded, no chipping or peeling at all.
I use very little reducer in my paint or primer. Try to stay less than 10%....and if it is hot I'll spray the green without any reducer at all.
Always wondered what the warning was about, now I know. If I was doing a complete refinish on a tractor, I might be more inclined to wait 36 hrs. But for one or two parts my method works just fine. I believe the recoat problem only shows up between say, (a guess here) 2hrs and 30 hrs. after putting on the primer.
