There are some decent spray "coatings" out there. I haven't tried F11 yet, but Ive used Sonax spray and seal, P&S Beadmaker, Carpro Reset etc... They all have different levels of protections and gloss. Don't think you can go wrong with any of them but my experiences are slightly different since I have Cquartz Uk 3.0 ceramic coating on my Jeep and all my vehicles so my results will be different
was going to order then read the reviews not on their site and they are horrible.
I opted for the Mcguires hybrid ceramic $15 vs $90
First step was clay bar treatment, low speed polish, clay bar again, then followed instruction on the hybrid stuff, it looked great but not amazing.
It said the stuff will take a while to cure, the next day the finish was amazing, have not had to wash with soap in 5/6 weeks.
Back to F11, I read that less is better and I think the example vehicle they used was an F250 and it said should not need more than 4 oz.
It does take way more than 4oz for a Jeep for sure. I had already done a clay bar a couple of months ago. I don't think it will last like a good old hard way, but way easier to apply and I believe shine is better. Another plus is how well it cleans stubborn bugs off the windshield.
There is another product called The Last Coat that works better and is less expensive. I've been using F11 for a couple years on my motorcycle but it doesn't last very long in rainy areas. The Last Coat lasts longer and they also make a car wash solution with the finishing product infused the soap.
