PPF (paint protection film) is a clear, self-healing film that absorbs chips, scratches, and road rash—ideal for high-impact zones (front bumper, hood, mirrors, rockers). Ceramic coating is a liquid nano layer that adds gloss, UV resistance, and easier cleaning but won’t stop rock chips. Yes, you can ceramic over PPF for the best of both: impact protection + slick maintenance.

Vacuum first with a soft brush. For leather, use a pH-balanced cleaner and microfiber; condition lightly every few months (avoid greasy dressings). For Alcantara, use dedicated fabric/alcantara cleaner, minimal moisture, and dab—don’t scrub. Never use household detergents, silicone shines, or steam directly on sensitive trim.

Start with OEM specs (width/offset/diameter), then test changes using a fitment calculator and manual measurements at full lock and compression. Keep offset within a safe window, match tire sidewall to intended ride height, and align with modest camber if needed. Roll fenders only when necessary; verify brake-caliper clearance before buying.

Pre-rinse, then use a snow foam pre-wash to loosen grit. Wash with the two-bucket method, a plush mitt, and pH-neutral shampoo. Rinse thoroughly, blow off standing water, and pat dry with a clean drying towel. Top with a quick detailer or silica spray. Separate towels for wheels/exhaust; never wash in direct sun.

Tasteful, reversible mods (vinyl wraps, PPF, removable badges, non-invasive lighting) usually help resale if installed cleanly. Keep OEM parts and document work with photos/invoices. Warranty coverage typically remains for unrelated systems, but any mod that causes a failure can be excluded—so choose quality parts and pro installation for electrical or safety-critical items.
