How to Prepare Your Car for a Show

A clean engine bay and the right small touches make a bigger difference than people expect. Here's the full prep checklist, from a week out to the morning of.

A Week Before

The biggest prep mistakes happen from trying to cram everything into the night before. Spreading the work out over a week makes the whole process far less stressful and gives paint correction or detailing products time to cure properly.

🗓️ One Week Out

Wash and clay bar the paint if it's been a while since the last full detail Apply wax or sealant — most need 12-24 hours to cure, so do this early Check fluid levels and top off anything low Address any small mechanical issues — squeaks, rattles, or warning lights Order any small parts or trim pieces you've been meaning to replace

The Day Before

🗓️ Day Before

Vacuum and wipe down the interior thoroughly Clean the engine bay — degrease, wipe down, dress plastics and hoses Clean the wheels and tires, apply tire shine Clean the glass inside and out — streaky windows show up badly in photos Check tire pressure Pack your show-day bag (see below) Cover the car overnight if it's garaged to avoid dust resettling

Morning Of

Resist the urge to wash the car again the morning of unless it's genuinely dirty — most of the work should already be done. The morning is for final touch-ups, not a full detail.

🗓️ Morning Of

Quick wipe-down with a microfiber to catch overnight dust Final pass with quick detailer spray on paint Check tire shine hasn't dulled overnight, reapply if needed Double check fuel level if you have a longer drive to the venue Leave earlier than you think you need to — good parking spots go fast

What to Pack

A simple show-day bag saves you from scrambling if something needs a last-minute fix:

Microfiber towels (at least 2-3)
Quick detailer spray
Glass cleaner
Tire shine
A folding chair
Sunscreen and a hat
Water and snacks
Registration/insurance documents if required by the show
Cash for entry fees, food trucks, or vendor tables
A canopy or umbrella if the show runs midday with little shade

Extra Steps for Judged Shows

If you're entering a judged competition rather than just a casual cruise-in, judges typically look closer at a few specific things:

Engine bay detail — this is one of the most heavily weighted categories at most judged shows. Degrease, dress, and make sure nothing looks neglected.
Underside cleanliness — some judges will check under the car, especially at higher-tier shows. A quick pressure wash of the undercarriage can matter.
Trunk and interior detail — don't neglect the trunk just because it's less visible. A clean, organized trunk reflects well.
Consistency — judges notice when one area is immaculate and another is neglected. Even coverage matters more than perfection in one spot.

Small detail that matters: bring a spray bottle with quick detailer and a towel to keep in your trunk during the show. A quick wipe-down between judging rounds or before photos takes two minutes and noticeably helps.

The Bottom Line

None of this needs to be perfect — most car shows aren't about flawless presentation, they're about sharing something you put real time into. That said, a clean, well-presented car always gets more attention and better conversations, judged show or not. A little prep goes a long way toward enjoying the day instead of stressing about it.
