View attachment 20939I have Optimum GPS, bought a 1/2 gal of the product about 7-8 months ago, right here from AG. I did my white 6x12 Cargo Trailer with it, and used my PC DA with the cruddy throw away Pad-Plate that comes with the machine. (figured it would be good for something like this, and it worked OK)
IMO, GPS is nice AIO product, it worked easily enough both on, and off, and got out mucho dirt, and film hazing off the trailer, which had never been done like this, only by hand with waxes. It didn't take out bird bomb etching, but I didn't expect it would.
I believe it to be a mild polish, and as far as longevity, there are probably products out there that might last longer. I have no empirical tests to confirm how long it lasts?
The Rotary still might be the best method to extract the best from this product versus hand application, because I feel the polish content is relatively mild. Perhaps something like a foam waffle pad, like one would apply a glaze with.
I later did top with Opti-Seal, hoping for longer protection. Whether this was correct to apply Opti-Seal directly over GPS I cannot say? Perhaps not, but I encountered no issues with the Opti-Seal application, no hazing, or streaking-etc.
Hope this helps,
Mark
