Repairing Frame Paint

[Tmwoodall]

So the story in a nutshell is this: I started a frame off when I was 17, with more want-to than know how. I stripped via wire wheels the entire frame. I primed it and it looked great, only to find huge flakes in the primer the following day.

Turns out you have to degrease metal, espcially 35 year old previously grease and grime soaked metal, prior to painting.

So I let it set and scraped and took off everything that wasn't cured and bonded REALLY well. Degreased and painted it.

Roll forward 7 years and I had to abandon the project for college, and then not having a garage. I just had it delivered a few weeks ago, and am taking it back to frame off to redo some of my previous progress. Turns out a few more smatterings have found there way into flaking off as it sat. At this point I suspect anything that it is going to loose it's bond, has lost it.

So my question is this, on the flakes what is the best way to repaint them? Sand down the edges around the flakes in an attempt to feather it? Use a thick primer to make up the depth? Tape it off right along the edges and just shoot it?

If your working with a bare frame. Just take the whole thing back down to metal. Get yourself some wax and grease remover and then wipe the entire thing down before you try to paint it. Depending on what your looking for. You would probably be better off to just send it out to be powder coated. They will sandblast and clean the entire frame before coating. Paint scratches way too easily especially on a frame. Putting painted parts together is nerve racking. I would call around you might be surprised at how cheap you can get it blasted and powder coated.

I am not taking it totally back to bare frame. I already have the brakes finished, the suspension installed and set and the motor/tranny in place. The paint I used, though not nearly as durable as powder would be I think will suit my needs. I used a tracter enamel with a hardener in it. Where it is stuck, it is stuck REALLY well. It doesn't scratch that easily either.

I am more looking to fix my mistakes than start from scratch on this one. I had in mind either buying a quart of the same stuff, or using Por15, or Eastwood's frame enamel on the affected areas.

With that in mind, anyone have guidance/suggestions?

If its in the budget, blast it and powder coat it. You'll never touch it again!
