Body Work Tutorial

Now, as far as the rust goes, it's always good to understand where and why this happened to the past paint job so, we don't recreate the issue. There are many reasons why this could have happened.

1. Panel was stripped and left bare for too long. ( I recommend sealing ASAP)
2. Moisture or contaminants from spray equipment.
3. Panel was not properly treated with a good primer.
4. Last painter sucked. LOL

So, these small specks are why I always believe in using a good primer, not some (as cheap as possible) primer... you really do get what you pay for in this industry.

As far as fixing these rust spots, you have a few options.

1. Sand panel until they are gone (or as close as you can tell)
2. Grind panel with some sort of abrasive wheel (this may require you to do filler work if it is taking metal from the panel).
3. Chemically treat the area with an acid wash. (this is hazardous so be careful if this is your approach).
4. Treat with a rust "converter" Not my personal choice.

This car is not terribly bad so I will continue to sand the panel with the mud hog until the rust specks are done. Each car will be different so you just have to do what you have to. Remember, the metal work is the FOUNDATION of a good paint job, and everything relies on the metal work, so take your time.
