DIY Car Hack: Fixing Big Rusted Rocker Panels For Less Than $20! No Welding.

How To Fix Big Rust Holes on Car Without Welding Under $20 — by ‘Lukas Lenner’. First, using a grinder, grind the rust to prevent more rusting in the future, and then fill in the holes with the expanding foam. Leave it overnight to dry completely then once dry and stiff, cut off the excess using a kitchen knife (with teeth). Next, smoothen the edges and apply coats of body filler (mixed with cream hardener) as necessary. Wait for it to dry. The last part of this process simply involves making the surface even and smooth with a sander, and then painting over the filled hole.

USEFUL TIP: Let the vehicle sit for 1-2 days after you cut the foam. This will prevent cracks in body filler due to foam shrinkage !!!Lukas Lenner
