Yes, it not only provides protection but also restores.

Wheels can be painted, chrome, powder coat, naked aluminium, anodized etc., so why not on paint (body)?  Fair point.  Technically you can, but won't be as durable as say, CQUK, on paint.  That's because Dlux has other additives in it for it to bond better to multiple types of surfaces mentioned above, and needs to have the chemical make-up to darken trims whereas CQUK doesn't need all of the additional 'stuff', it can purely focus on Sio2 content, gloss and durability.  But can I use CQUK on wheels then?!  Sure, if it's clear-coated, but sometimes the face of the rim or spokes are cleared but with a raw barrel finish.  It's just best to stick with DLUX, you can do your trims at the same time, might as well!

Yes, you can, but does it make it 'glossy'? No, it won't. Imagine putting lotion on your dry hands; it rehydrates and enriches the skin without making it oily—that's what DLUX will do. Matte finishes will remain matte, but the complexities will look richer. When working on matte finishes, do not let the product set for too long; wipe on and wipe off with no set time.

When it comes to matte wheels, it's essential to coat them. The challenge with matte surfaces is their texture, which tends to attract dirt and debris, making them harder to clean than smooth surfaces. Coating them with DLUX helps maintain and protect the matte finish.

Yes, see above.

Wheels: Chrome, metal, aluminium, steel, anodized, powder coated, Titanium, cleared, painted etc.

You can also apply DLUX on brake callipers, exhausts, suspensions, fake plastic chrome, head lights etc., anything exterior really, besides windows.

IronX, Reset, and Hydro2 Lite.  Hydro2 Lite can be used monthly to keep the coating going and the winter salts off.

You should, you're applying something that hardens after all.  Missing a spot would result in high spots (can be hand polished off with Carpro Fixer).
