Learn how to repair rust on car. In this video and post I will cover the best materials to use for rust bubble repairs that are less than 1.5″ in diameter.
This whiteboard presentation was made to get to the point quick.
In my VIP training videos I completely reveal the step-by-step strategized that you need to bang out a successful rust repair patch job.
Step 1 Grind Off Rusted Area Down To Metal
Use a stone or coarse 16 grit disc for your grinder.
Grind the entire area clean. Be carful and watch your disc rotation. You want to grind away from an opening not into an opening.
Especially if your using a disc. You may have the chance of the disc ripping from the jagged rust edges and propelling toward you.
Grind two to three inches around rusted area to give yourself a nice working area.
Step 2 Rust Treatment
Yep I said that right. Of you have some white vinegar at home simply mix it 50/50 or so, give or take with water then get a rag and dunk it in to your concoction and wipe on rusted area.
Let dry for ten to fifteen minutes, scuff with sand paper, then you’re ready to lay your Bondo Hair product.
Step 3 Filling Holes With Bondo Hair
Be sure to tap high corners down before filling. Actually you should do this before you start cleaning it with your solution rag.
Also be sure to get to the back of the panel if you can. Clean it, and repeat the same process if possible.
If you can get to it and sand down your filler, then great! If not, try and seeing if you can spray some rubberized undercoating over the back to seal it from the elements.
Here’s what the rubberized undercoating looks like.
That’s basically it. Now you’re ready for some primer and paint.
This is how to repair rust on car.
Of course, this strategy is totally different from repairing larget rust holes.
Larget areas require sheet metal patches and some welding. I usually love to spot weld.
I also have complete videos on these steps above plus more all in our Totally Awesome LABAP VIP course.
