I used Halo to coat my matte colored vinyl wrapped Lincoln Continental. Halo was recommended by the wrap installer, and offered as an additional upgrade service. I went the DIY route as I have experience installing ceramic coatings. Halo was very easy to work with and would not be difficult to use for a beginner. You will use more of this coating on vinyl than you would a traditional coating product that is made to protect paint. Two coats is recommended for the best durability. My vehicle is a large sedan (with a 6" factory stretch) and I used close to 90 ml. to do two coats (which included my wrapped door jambs). It is recommended to apply a very liberal amount of this coating to vinyl, as it will soak it in. Plan to use more than you initially expect is my point. Halo did not alter my matte finish and makes it feel slick and well protected. This car is a garage queen so I cannot really comment on durability but I expect it will last many years. There are other coatings that are safe to use on vinyl wraps, but this is the first (and only?) coating that is made specifically for vinyl and PPF. Highly recommend.

Having been an avid user of Car Pro products, I wanted to take a stab at Gtecniq products for the PPF portion of my car. The process as to any ceramic coating is similar to other brands. Halo was very easy to apply and wipe off. It was around mid 80s and flashing was pretty much instant. I also tried halo on plastic pieces and it performed well, the plastic pieces were not darkened heavily as a trim restorer would do. In essence it was a very easy application process and impressed at how slick the PPF is. Usually it's a bit grabby but now it feels like ceramic coated paint. Impressive.

I have done other Gtechniq coatings on PPF before with positive results, but when halo was released as the official PPF and vinyl coating I had to try it out. Halo is easy to apply. Even for those who have no experience, it is easy to apply and avoid high spots. I do recommend the carpro block and suede pads for most application surfaces. It is quicker and more consistent than the supplied Gtechniq applicator pad.

Prep work is pretty straight forward. Decon wash, polish if needed, panel wipe/eraser and you are good to go for application. For the application I do a vertical line down a CarPro suede pad on a foam block. Like CSL or EXO work in 2'x2' sections. Have one microfiber towel to buff inside the 2'x2' section and one to buff outside the section. Each towel has 8 clean sides. You should swap after each section and replace towels as necessary. Performance wise over something like XPEL ultimate or SunTek Ultra is more of a water bead applied to the film. Looks wise there is something a little extra added by HALO to my eye. If you have PPF or any variety of vinyl this is a wonderful way to provide long term protection.

For those new to ceramic coatings, HALO is great for a first time user. It's quick and easy to apply, plus it offers good working times which enable you to cover a fair amount of surface area on each section. Removing the product is similar to using a quality SiO2 booster. Using two microfiber towels, you can reliably prevent high spots and streaking. Combine EXO v4 with it for a bit more gloss and slickness.

If you are considering a ceramic coating for your car's paint, applying HALO and EXO v4 to the PPF first will provide an excellent opportunity to gain experience with the application process and build the confidence necessary to apply a paint coating.
