Hello, I would like to say thanks to those who make this site so informative. I have a two questions. First one, as I am sanding this car down with a DA and air file in areas I am hitting this red (terra cotta) sections that seem to be some type of body filler. This is mostly found on the roof and front fenders, not so much on the hood, doors, etc. It acts mostly like a skim coat and under certian areas under this red is a minimal white fillter. My question is, does this sound like fillter and should I leave it or keep sanding it off?



Second question is related to the pictures. The front fenders have a section that it a bit rusted. Once the skin of the rusted metal was removed, you can see how brace on the fender is pitted with rust. I am not sure what the best thing to do is in this situation. On the lower part of the area is not rusted except through the pinch weld on the inside, and the skin is not bad in this area I have no problem putting a patch on the skin, but the brace is throwing me off a bit. I did cut a little area out of some of the larest rust areas.

Thank you

The red stuff is likely to be Nitro-Stan, a lacquer based spot putty. Easy to work with, worked great for the right applications, but there are better products for the modern supplies. Take it off.

looks like you cut thru the brace near the fold over flange, and I bet it's rusted as well. Did it cut thru where you noticed it cutting a little too easy? If so it's rust.

To be thorough you'd have to buy a patch for the brace and a patch panel for that area and wrap it around the support. It should already be bent in that area. If there's nothing considerable to line up line it up at the bend and then scribe/cut/ etc.

If you want the easier route just clean up the cut and make a patch but weld up that brace where you cut thru first. If you want to learn how to make patch panels check this out. It's in there somewhere.

here's one I did with the brace

Thanks for the suggestions. No problem making the patch, and thanks for the vid link. I think I am going to cut out as much as I can on the brace and patch in a section. I will probably have to leave the lower section of the brace where it pinched to the fender. I have read and read the rust wiki and we all know that to get rid of rust you have to cut it out.

Also thanks for giving me some insight on the body filler stuff, I was told to leave body filler but obviously do not want it to mess up the paint.
