As stated above , I'm looking for a good and safe APC for cleaning powder coated suspension parts , but will also be using for the undercarriage as well .... Looking for what you guys use and have seen the bests results from, thanks
You should be fine with almost any APC on powercoated parts. I clean my suspension (coilovers, sway bars, etc.) with Optimum Power Clean (OPC) at 3:1. Personally, OPC has the best balance of strength and safety.
