Like the Nufinish for rainx hack. May try that.I'm a fan of Nu Finish. However, the directions state it can be used in sun or shade. I would avoid sun--it hazes white with more elbow grease to rub off. In the shade it barely hazes. Cloudy day or in the garage should do it. Also, given it's a polish it probably contains some micro abrasives. It's best to avoid circular motions to avoid swirl marks. Wipe on and off front to back is best. Ceramics, and clay for that matter, likewise have micro abrasives. And when you get down to it, anything you rub on a car with a microfiber is to one degree or another abrasive. Nu Finish does not give me any particular concern.
I applied the first treatment to my CX-5 in the fall of 2020 and then again in spring of 2021. It's still beading nicely so I'll wait until next spring to reapply. There may be other products that add a bit more shine but it's still plenty shiny. @Goguinness might have the right idea for the fastidious--an extra-shiny spray product between Nu Finish applications. I don't bother.
I also use Nu Finish on the exterior windshield about every 6 months after washing and rubbing down with alcohol. It's not quite as effective as Rain-X in terms of sheeting and beading, but it provides some of that and seems to elongate blade life. I'm still on the original blades at 12,000+ miles through one winter. On the other hand it doesn't leave the permanent shadow on the windshield I've experienced with repeated Rain-X applications on other vehicles.
My personal hack--Nu Finish to remove off-gassing and smoke haze on the inside of the windshield and front door windows. I've tried other youtube hacks, like Magic Erasers, on older cars and Nu Finish works better and faster. Two on-and-offs have gotten rid of about 90% of a heavy haze on those older vehicles. I've not tried in on rear tinted windows for fear of possible damage but you don't really see the haze on those anyway.
Thanks. Sounds like that would really work well.I may be one of the only ones who's had a less-than-ideal experience with TW Ice Seal n' Shine. I tried it a couple of times and just couldn't get it to stop streaking for me. I must have been doing something wrong, but no idea what.. it was applied post wash, with the car in the shade or in the garage, in warm weather, using high GSM microfiber cloths.
I've never used NuFinish, but I've seen tests where it's outlasted some ceramic coatings with regard to durability. Very impressive product.
@Jack Rabbit, I'd suggest NuFinish first, with Meguiar's on top, if you want to use both products. NuFinish contains some mild abrasives, so by applying NuFinish last, you'd likely remove a small amount of the Meguiar's that was previously applied. IMO, NuFinish is best used as "base layer" for durability and long lasting protection, with Meguiar's on top as a "sacrificial layer" that adds some gloss and depth.
