If you're tackling car repairs at home, having the right aerosol sprays on hand can make your life a whole lot easier. These pressurized cans deliver targeted performance—whether you’re degreasing, protecting, lubricating, or painting.
But with so many options out there, how do you know which ones you actually need? We’ve broken down the top types of automotive aerosol sprays every DIYer should keep in the garage, plus what to look for when buying them.
1. Brake Cleaner
Brake cleaner is one of the most essential sprays in any DIY toolkit. It quickly dissolves grease, brake dust, and oil without leaving a residue. Use it to:
- Clean brake rotors and calipers during pad changes
- Prep surfaces before applying adhesives or coatings
-
Degrease metal parts during disassembly
Choose a non-chlorinated version for general use, or a chlorinated formula for maximum strength (but make sure you have ventilation).
2. Penetrating Lubricants
Frozen bolts? Corroded fasteners? A good penetrating spray (like PB Blaster or a OneSource equivalent) breaks the rust bond and frees stuck components fast.
Use it on exhaust bolts, suspension hardware, or anything that hasn’t moved in years. Many options double as moisture displacers, too.
3. Undercoating and Rust Protection
Protect the underbody of your vehicle with rubberized undercoating spray. These create a flexible, durable barrier against moisture, salt, and road grime.
Some products are paintable, while others remain rubbery. They’re perfect for:
- Restoring factory-style protection
- Coating wheel wells and frame rails
- Preventing corrosion in exposed metal areas
4. Spray Paint for Automotive Touch-Up
Need to touch up small chips or parts? Aerosol paints formulated for auto use offer solid coverage and fast drying. Always prep the surface with sandpaper and primer, and finish with a clear topcoat for added durability.
5. Silicone and Lithium Grease Sprays
Silicone sprays are ideal for door seals, window tracks, and plastic components—they reduce friction without attracting dirt.
White lithium grease sprays are better for high-load metal-to-metal contact, like hinges, latches, and hood struts.
Final Thoughts
Aerosol sprays can make tough automotive jobs easier, cleaner, and more precise. Stocking your shelves with the right formulas ensures you're ready for everything from minor repairs to major maintenance.
