Liquid Wax
The combo is to put Jescar Power Lock Plus as the base layer (polymer sealant) and top that with 2 coats of 845. This looks better than anything else I've ever used outside of maybe Swissvax Concorso, but lasts a lot longer and is more durable. If you're not wanting to jump into coatings, Power Lock Plus and Collinte 845 is your most legit option.
A couple of things to note:
- One bottle of this should last you the next ten years of your life. I think I've spilled more on the floor than I've actually used on my cars.
- It will change state depending on the temperature it is stored. That is normal and fine to use. Run the bottle under warm water if you need to soften it up.
