repairing a steel grill

[dotcentral]

I have a steel grill that is straight, but has some major pitting from rust. It just got back from being sandblasted, and has a coat of rustoleum primer. I'd like to fill the pits in and smooth it out. Will body filler stick well to something like this? Will it stick to the rustoleum? I would also paint the grill with rustoleum to finish.

I dont put body filler ontop of paint. Havent really had much luck with spot putty either. How deep and how extensive is the pitting??
I would take my time and fill in the pitting with the same rustoleum primer using a small paint brush, and using little blobs of primer as filler.
Let it dry between blobs of paint, and sand flat after its filled and thoroghly dry.
Labor intensive, but you do it once and thats it.

stript the paint back off of the area. then i would take a welder on real low so as not to burn though and add just weld in some small beads to fill the pits. then grind down the spots until flush. some body filler and paint your done.

Strip the paint offf, then use JB Weld in a thin film to fiil the pits. Snooth it out and paint it.

how about POR 15 dabbed in those areas?

how about old school and using lead? you also can use a evercoat product called final glaze. it comes in a little blue can and has a small tube of hardner. their is also a product called all metal with hardner its metal fileings in a bondo like product. if its warm in your shop or outside go very easy on the hardner on both products.

I've read in several bodywork books that using bodyfiller in pitting is perfectly acceptable, as long as the metal isn't rusted through. and you want all the rust gone, or neutralized. Good luck!

I had a similar thing happen on an old truck years ago. The guy that had it before had painted over some rust pits he had sandblasted. I hadnt heard of paint stripper back then (I confess, I still aint uptodate enough to have used it yet) I took the torch and burnt the paint off (careful not to get it too hot and warp it) Used JB Weld on the pits and its still good today, 25 years, 8000 buckbrush trees,32 000 000 grasshoppers, 3 washings and 400 cows later.

SO long as your not chroming the grille body filler is the way to go. Get the biggest majority of the dent out and then use body filler then prime, sand, and repeat process until it is perfect or to your liking.
