Painting a pitted hood

[Daddiojoe]

I've got a layer of Rustoleum primer, a couple of layers of primer filler (rattlecan) and a couple of layers of primer sealer on my evil old junkyard hood and it still has pits that are visible if you look at it right. Feels smooth, but I don't want to spend money on paint just to perpetuate a pitted surface.

Any suggestions?

Thanks

glaze putty.

after all that i would buy a high build primer and start blocking it out. use a guide coat and go slow with 320 grit paper. better yet, wet sand with 800 and block it with a guide coat. you'll get every pit covered over that way.

Block sanding will be mandatory.
For large pits a glaze filler is the proper fix.
Just make sure it is a glaze with a catalyst.
The single parts glazes are pretty poor quality, and shrink.

why not strip, and use an etching primer?

etching primers promote adhesion - he is trying to hide. he'll need a high build primer or a glaze coat of something to hide pits from rust over a large surface area.

The etching primer is an excellent base, for adhesion as Ben mentions.
It will not hide. It is an excellent base for a glaze to sit on top of. Fillers
and glazes aren't usually designed to go on bare metal.

sorry, my time was cut short last time. What I have done in the past is completely strip the old paint and rust. I then fill the little pits with bondo, and sometime I have used fiberglass. I then block sand the area, seal with an etching primer, block sand again, use an epoxy primer, block sand, then spray the color coat. It is A LOT of sanding, but the results turn out beautiful......

Thanks for the tips, guys. Especially on the two-part glaze putty. The problem is that the pitting is there pretty much for the entire hood. And I'm lazy and impatient (often).

If you are just worried about the pits at this point, you could use a filler and then sand with a DA to
get the pits filled. Then you could follow up with the normal block sanding and guide coat to the level
of straightness you want for the entire hood.

There is also a poly filler you can spray, which is basically spray on Bondo. You would spray a few coats
to fill the pits and then sand off the excess. If you have to do the whole hood, this would probably be a
more efficient way, compared to smearing glaze over the whole hood. I haven't used it myself, but the
body guys used it on my Fury, and it is razor straight now! Not sure what the most cost effective would
be though.
