If you are restoring a classic car, there is likely going to be some rust that needs to be repaired. The rust may only cause surface damage, but with older cars, it is likely going to be worse. You will need to choose from different choices of auto body repair solutions for this rust damage, such as patching in sheet metal, using a body filler or completely replacing severely damaged sections of the bodywork. Here are some of the different options for repairing the rust damage and when they work best.
1. Removing Minor Rust Damage and Using Fillers for Repairs
When the rust damage is minor, you may want to do minimal repairs and keep original parts. The first thing that needs to be done is removing the rust and cleaning the metal. Once you have the raw metal exposed, auto body filler materials can be used to fill in any pitting or small holes. This type of repair is best for minor repairs where they are not too visible, such as at lower body panels with flat surfaces.
2. Welding in Sheet Metal Patches Where Rust Has Caused Holes
Sometimes, the rust may cause larger holes in the sheet metal. When you begin doing repairs, they may seem small but grow as you clean the rust away and expose the extent of the damage. When holes from rust are too big to be patched in using body filler, the damaged metal will have to be cut out and new pieces welded in. This type of repair is good for areas where replacing an entire body panel may be too difficult, and repairs with fillers cannot be done. They are also good for repairs to areas that are not noticeable, such as floor pans and trunk areas with rust damage.
3. Cutting Out Severely Damaged Panels and Replacing Them with New Parts
There are also times when the rust damage may be too severe for using fillers and welding new metal is not ideal. Areas like fenders are places where repairs may be noticed once the final painting is done. Therefore, you may want to consider completely cutting out the panels and replacing them with new parts. You may also want to consider replacing parts for fiberglass or carbon fiber parts to make your car lighter.
These are some of the different options for the repairs of auto body damage and where they will work best. If you need help with repairing severe rust damage, contact an auto repair service to ensure work is done correctly.
