I had that happen on the last frame that I painted and couldn't figure out why it happened. It was just one section. I ended up sanding that part back down and I was able to blend the paint to my satisfaction.

Either incompatible under coat (primer), or old finish coat, or something had an argument with the solvent you used or prepped with

It was a new on me. I prepped the whole frame the same way, or at least thought so. The problem area was about 9" along one of the front uprights. It's just another example of problems that pop up when you are painting something.
 
I use simple green to clean my grill frames and many other parts before I spray them. I just clean with the SG and rinse well with water and then make sure they are completely dry before spraying.

Degreaser like simple green?

While I know some may like it, I don't. I do use SG in my ultrasonic cleaner to clean mixer pieces and smaller gear boxes. But there is no way I'd risk it prior to spraying enamel. I'm a firm believer in keeping anything with water away from what I want to spray. After all it's water that caused all the issues in the first place. If you don't have a store like our Farm & Fleet or Fleet Farm look for a place that mixes automotive paints for body shops. They'll put you onto proper chemicals to be sure. But, I'd never used a water based cleaner or one that has an affinity for attracting moisture.

I accidentally used simple green as a degreaser for a cookbox before and it was fine. I say accidentally because I had still intended to use brake cleaner or mineral spirits on it but forgot to. I think the key here, as Bruce mentioned, is making sure it's completely dry. In my case I didn't paint the cook box until the next day after cleaning it with simple green and rinsing it off with water.
 
Often times the wrinkle effect is caused by too heavy of an application. Especially while using aerosol cans. The solvents evaporating (or attempting to) basically cause pressure under a drying layer of paint. Yes, moisture and preparation can cause it too, but the most common cause is too heavy of application and thus why generally speaking it is in a localized area. Same things happen with the high dollar paint as well.
 
My issue with water based cleaners (whether SG or anything else) is especially on castings, castings are porous and you can never fully get it all. May not see the reaction immediately but possibly "down the road". When my dad was a partner in a plant that did metal finishing of all kind of pieces they used a caustic soda of some type but then the pieces were rinsed with high pressure fresh water and then baked in ovens at 400F for quite some time in huge walk in ovens.

Mineral spirits work?

Better than water based or hydroscopic but with a caveat. Mineral spirits are just kerosene that "knows somebody". Or basically highly refined diesel which tends to have a slightly oily consistency. But yeah still far better than water based or water attracting. But what is the aversion to simply getting something better? If you were to look in my cabinets you'd see a variety of solvents and cleaners for specific purposes

Just was trying to use something I already had/save money if possible. But I’ll run out this AM and see if I can find that grease/wax remover.
