Andrea about 3-4 months for me.... Fk1000 P has a bigger longevity... but Bilt Hamber has a better looking... overall Both are Ok... i put Sonax BSD as a last shield and it is amazing hydrofobic cover
How did it look like before washing? I applied the wax 2 weeks ago and the beading and sheeting looks so much worse already. It rained every second day so my roof actually still looks clean.
This video is made after was with Chemical Guys Citrus Wash & Gloss (this is a very good product from CG, others aren't so good). So, the surface is like at the date of application. I have on channel another video that was made before the washing process and even though the surface looks clean, there is not the same sheeting because there are contaminants that have bonded to the surface and need to be removed. I have had a durability of about 3 months with this wax but this longevity depends on many factors that are generated by car maintenance and road conditions.
