I will be storing my car outside near the ocean. Are there steps I can take to prevent mold and condensation formation inside of it?

Start by cleaning and waxing your vehicle, and then just maintain that level of cleanliness. You're near the ocean, so rust and corrosion forming due to the salt in the air is your vehicle's worst enemy. Today's spray waxes, which are more like a sealant than a wax, are easy to apply, and you can apply them to all of your vehicle's exterior surfaces. You can finish an average vehicle in about 15 minutes with the new spray waxes on the market. Reapply the spray every month or two. Run your vehicle for 10+ minutes at least once a week to keep rust and corrosion from forming inside your engine.
