At boot camp, you must score higher than 60 and must score above 50 on future tests. You can see charts on how many points are assigned for your performance in the various events on page 29 of this pdf copy of the US Navy's Physical Readiness Program document from July 2011.
Scratch Wizard , an online company that sells DIY touch up kits, estimates the cost to repair a clearcoat scratch is generally between $150 and $300 Schwartz says the cost to repair a deep paint scratch can range in price from $300 to $900.
Or have an auto body shop do it for you ($50-70). If the scratch is a deeper one, but has still not reached the paint layer, you will need some wet/dry sandpaper to get rid of it. The sandpaper will cost around $10, with wet 2000 grit being preferred. Soak the sandpaper in water and sand the scratch. You will also need rubbing compound to get rid of the sand scratches, as well as polisher so that you can shine it when you are done. All told this will cost about $30 to do it yourself, which is a fraction of the $150-300 that a body shop will charge you.
