Yes they work well and yes they are often pretty toxic.
The 1k ambient moisture cure is less toxic than the 2 pack I believe.
That's why I chose POR-15.

Not sure if the 1k is actually less toxic than the 2k, or if it's just because the 2k is usually sprayed and therefore more likely to be inhaled.

Just for the archives.
I tried a 3M "Cubitron" abrasive flap wheel and it clearly cuts better than old style Aluminium Oxide and Zirconia abrasives.
May try to find an even better solution, but the Cubitron can do the job.

Cubitron is awesome stuff! If you can find it, cubitron II is even better.

I once installed a robot at the 3m plant in Alexandria, MN, where they manufacture it.

The number one reported workplace injury: abrasions!

It was actually version II, didn't spell it out because there didn't seem much interest, only added the post to help if someone searched in the future.
But yes, it is excellent, thank you for your contribution with the robot installation
Now I am off to buy some more, a bit finer, it cuts quite fiercely.

I've been using the 3m self etching primer, made an accidental discovery; if you let it bake under a lamp for week or so it becomes hard and seems to grab paint better. The can says you can coat soon though like in one hour.

available at lowes and/or home depot for $5 , its Rustoleum brand if you want to experiment.

The 3M is about $15 if I remember. But its only a slightly better.

If you use an etching primer under paint, the durability Is almost "powder coat".

The only 3M primer I can find is a dental repair product, hence my query and "Kay Pirinha's" (I assume).
My suspicion is that any primer that contains an etchant must be a compromise.
The etchant won't be as effective as a product that only has to etch, and the paint chemistry is constrained by the etchant pH.
But it is hard to know which of the several primer systems works best.
Zinc based "cold galvanized", etch primer, polyurethane, etc.
I have opted for polyurethane, seems to be the "gold standard" for industrial work, and, in particular, boats in salt water.

Best wishes
David
