I just started using this products and its Winter, so I have not been able to "test drive it yet". Will update my review when I get out among the dust, dirt, and bugs this Spring.
I ride a Harley-Davidson Fat Boy Lo, which is why I purchased the ReJex. I first used it on my motorcycle and liked the ease of application [wet cloth; easy on the amount you apply; spread thin layers] and the ease of removing excess dried residue - leaving a high gloss shine. My motorcycles looks better now than when I got it new.
Then, I decided to purchase a Gallon size of it to re-fill my 16 oz bottle even though I have now covered my Jeep Grand Cherokee with it and still have not used but 55% of the smaller bottle of ReJex, so it goes a long way.
I wish I had purchased this years ago. My Jeep looks incredible, and the surface is so slick, I can't imagine all the bird droppings, and bugs I have had to contend with over the years being more than a damp paper towel-swipe to clear these lovely substances and keep them from eating up my paint job.
If I had found this website / product last Summer, I could give a more thorough review of this product keeping the droppings and smashings from my Jeep and Harley's paint, but I will have to wait until I start riding again and for the birds to start blasting again in the Spring.
I love the ease of application and ease of removal of ReJex, just don't leave it on for 2 days before you remove it. I did this with my Jeep and it was harder to remove. My bad. With my motorcycle; I left it on for about 20 minutes and then it just wiped off easily.
I also did my Shoei Neotech Borealis helmet [because it needs ReJex as well] and now its hard to hold onto because it is so slippery. I like to just sit, hold it, and run my fingers over the helmet because its much more slick than clean glass. It feels good too.
One more suggestion: I keep surgical gloves around the house to keep getting chemicals on my hands and I would suggest using them for applying this polymer, just in case it gets absorbed into your skin and a face mask or a ventilated area to avoid breathing in any of the residue - just in case.
As I said, I love ReJex and hope they keep selling it forever.
