There is a lot for this product is not to say, you get high-quality isopropanol 99.9% in a stablieren 5l canister. For isopropanol, there are numerous applications, on the one hand one can use it as a disinfectant. There are in the reviews already a few suggestions for mixing ratios.
I use the isopropanol mixed 1: 1 with distilled water for the auto care. After polishing I apply the mixture on the paint on to this to "disinfect" and so prepare them for the job of wax or sealant.
