It has been 2 years since I have been using these combo products and I absolutely like them.
The GYEON is great on black trims and The Last Coat for textured trims like mudflaps and unpainted plastic.
Ultra Lock has the best gloss I have tried. Place two coats on flat surfaces like the hood, roof, etc...
All are under $100, no need for ceramic coating services which is 10x the price.
