Try Soft99 Fusso dark light, around £20
if you're going for fusso dark probably more suitable to this colour than white... although dark its white! apparantly dark has a few fillers in it, and for all the debatables out there fusso is a sealant not a wax haha
Iv got a tin of the dark stuff, when I posted I thought they where called dark light and white light ...... but maybe not with out the tin in front of me . Didn't know it was a sealant either , but I'm sure it says sealant/wax in the ads
They do other products king of shine or summit like that , I believe there's a newer black one out aswell with better filling properties
More to the point you'd struggle to beat it at the price point and easy application.
This is Auto Finesse Tough Coat applied over Poorboys Black Hole glaze. I have tried various waxes and none seem to offer the reflections and slickness of a sealant on this colour. Nattys blue was the biggest waste of time of them all, minimal visible improvements and lasted around 2 weeks.
Ive heard and seen good things from Auto finesse Essence which is also on budget, I personally have not used it, but I do use a lot of their products, I can vouch for their spirit wax and illusion wax - both are awesome!

i've got a pot of essense and its not bad but wouldnt say its worth its price there is a lot better stuff to use imo and i found durability wasnt the best only got 8-10 weeks out of it and thats with proper prep too
