Routine radiator flush n fill - info double check

So this is what wjjeeps says: (paraphrased)

"Recommended mixture is 50/50 ethylene-glycol and low mineral content water. Only glycol base coolant with corrosion inhibitors called HOAT is recommended.

If the percentage of coolant is lower than 44 percent, engine parts may be eroded by cavitation, and cooling system components may be severely damaged by corrosion.

Mopar Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769) may not be mixed with any other type of antifreeze. Mixing of coolants other than specified (non-HOAT or other HOAT), may result in engine damage that may not be covered under the new vehicle warranty, and decreased corrosion protection. Do not use coolant additives that are claimed to improve engine cooling.
(capacity: 1999-2000: 13.0 qts.)"

So I'm planning to just drain/fill the radiator & distilled water w/ coolant as this is a routine maintenance thing and no issues exist currently such as overheating, heat, leaks, etc.

My questions are:
1. About the additive Water Wetter. I realize what wjjeeps says is prolly taken from the OEM docs. The additive claims to be compatible with everything and provides benefits (though marginal) I'm interested in. Any first-hand experience with their claims?

2. The HOAT I'm reading about as acceptible as Zerex Z05. Any counter ponts? Other recommendations?

Both are fine. The additives dont do much unless you are running straight water and need to help lube the water pump. Have never seen it help temperature wise in my experience.

You can pretty much run whatever coolant you want as long as the system is flushed out well and no coolant types are mixed. Get the proper mix and you will be fine.

I've ran both water wetter and purple ice in my Thunderbird SC. There was a noticeable difference with the additive. The car was known for overheating issues since Ford made the radiator smaller to make room for the intercooler. Also, the PO added some type of stop leak that clogged everything up, possible adding to the heating issue. Between the first flush/fill, replacing the radiator, and changing the belts (some idiot engineer ran the hose though the belt) I changed the coolant at least 3 times, each time with one of the cooling additives.
I can say first had that they work - but i still probably wouldnt spend $10 on a little bottle of fluid unless i thought i needed it. Never ran it in any of my other cars or jeeps.
