Im going to cut out the rust and refill with bonda.The rust doesn't seem to deep but I will know more once I start to remove it.My question is should I use a filler like dynaglass or just use bonda to fill these holes?Can anyone recommend a good bondo?I'm not going to buy a welder and everything else to do this repair, bondo only.

if you're going to strip it down to bare metal, you should probably use some metal2metal body filler.

i advise against this tho. its really much easier to buy a body panel and pay a fabricator under the table to weld it in.

 

You have to remove all the rust, if not it will come back.

once you remove all the rust, you can spray primer over the bare metal or use bondo glass, aka kitty/tiger hair. It's body filler with strands of fiber and dries rock hard.

Use 36/80 grit to get the bondo glass roughly shaped then use regular filler over that. Prime then paint.

 

Excellent, thanks.
