Ok I gotta chance to use this stuff to wash my coated truck yesterday....
My official review: It Sucks.
So, we`ve had about a month straight of rain here in PA & I haven`t washed the truck once. It was pretty filthy... True to form, there were areas on the lower panels that weren`t beading well - didn`t matter if it was before or after I washed them with Bath +....
So, the directions for this stuff say to use like 20 ml in a "bucket". Just how big a bucket - who knows???? So, I decided to use 2x that much. No great results...dumped in about another ounce - no great results. As a soap it`s just Meh as well.
On the converse, I grabbed my spray bottle of HydroFoam 1:9 and pretreated the panel before washing it with Bath +; the difference was night and day. Anything I touch with HydroFoam in a spray bottle beads like crazy.
