Welded up some old nutsert holes in a panel and grinded them smooth... Now I need to slick it out with a little bondo prep and paint. Then I'm going to top it off with a little base coat clear coat...
Help me out with the process... there's etching primer, epoxy primer, filler primer, regular primer, sealer,etc. some of it maybe considered the same I'm not sure. I get the terminology mixed up. What's the difference between them? and what order do you use them?
I've never really brought anything down to the metal before but never really sealed it correctly. I've roughed up some clear with 600 grit or scotch pad and shot some primer then, base, and clear for a color change.

I always use etching primer... 3 or 4 coats... sand smooth and then use sealer.. May not be the correct way tho..

Not my field, but my understanding through listening to folks who paint is that the etching primer is what you use on bare metal.
Ben would probably be your guy here.

So, bondo, etching primer, sealer, then I'm good for base coat?
I used a primer one time that couldn't be sanded too well, it was kind of rubbery. It tended to "roll" instead of sanding off. I was thinking that was an epoxy primer.

Yep. You got it.
Typically mine gets bondo, etching primer, primer sealer, paint.
I wet sand the etching primer and sealer before paint.

No reason to use etching primer. Do your body work, put you a couple of coats of "filler" primer (use a lacquer base mixed up a little on the thicker side), block it down, get it smooth and top coat it with the same lacquer primer just thinned a little, 320 grit that and paint. No need for a bunch of fancy crap, just follow your instructions on the primer and bondo and you'll be just fine.
When you spray the filler primer, block it down with 180 grit either wet or dry. If you wet block it you won't be breathing in a bunch of dust but you will have more cleaning and wait time between new coats due to having to make sure you get ALL of the water and sanded material off of the surface. When you're done blocking everything and are happy with your final results, go over it with a few coats of the same primer just thinned down a little, sand that with some 320, clean the surface, spray your paint.

Went to the yard to pick up a window frame... Popped out the glass  It was pretty straight no dings or nothing, scratched my head at some bolt holes at the top. I guess I was so excited about junk yard hopping, I didn't notice that the top holes were nutserts from a damn light bar bracket until I got home. One of my many typical brain farts. 3 holes on one side, 4 on the other... geezz what dumb ass, where was my head!   That's what the ole miller welder is for...   I did decent, didn't use much bondo at all... forgot to get that shot before the primer, time for a few beers :beer:before I wet sand it...  |

That looks pretty damn good man!! Why you asking us for directions?? Well, it's been a about 8 years or so since I've done any body work. I didn't really know what I was doing then, but it turned out well. Learned mostly by my mistakes... Kind of feel like I relearning everything, but it's coming back. My intentions was to slightly water sand the clear with 600 grit, throw on some primer, base, color, and then a few coats of clear and call it good. I goofed and bought a bad frame and I had to sand some of it to the metal and do a little repair work. My main thing is I just don't want any rust popping through b/c I tend to keep my vehicles till they fall apart. And windshields tend to rust out even if they're done correctly. I might as well learn, because one thing I'm really good at is tearing shit up!  |

Just make sure you seal the primer and it should last a while without rusting...
