Removing minor dieback

[tguil]

According the the body shop owner and all of the paint troubleshooting websites, the "fix" is pretty much the same as orange peel...sand and/or compound and polish. If severe, sand and repaint. In my case the dieback is far for severe.

Bobby, from what I read this is a solvent trapping phenomenon, so it may not be a "top-down" defect that can be sanded away, if it is further down in the clear...

The way I visualized it was the slightly dull area was on the surface...

OH, I see, now I understand it better...Thank you!

I've also heard the term dieback called shrinkage or shrink back.

I've had success simply re-sanding, compounding and polishing. Here's the deal, if it's topical, you can fix it. If it's under the clear top coat you can't.


Hate to sound like a broken recored but here goes...


When I want to troubleshoot a paint defect I'll place a tape-line down and buff on just one side of it. Then inspect.

You're either going to see you're making a positive difference, a negative difference or no difference at all.

If it's positive, then remove the tape and continue fixing the affected area.

If it's negative, post back here what you're seeing, we might we able to tweak your technique or process.

If there's no affect at all then it's likely the problem is under the clear.

Find a friend with a really nice camera. It can pick up stuff you can't see with the naked eye. I'd love to see what you're talking about.

Here's picture 5 from above...



And here's two full size sections cropped out of it showing the sanding prep marks in the paint after the paint dried and shrunk back a little. All of these defects sanded and buffed out.

Thanks, Mike.

I'll try to get at it soon. It's not even close to being as bad as the pics you posted

One more thing. With Meguiar's Ultimate compound should I go ahead and use my Meguiar's maroon cutting pad or wait and order an Optimum or Meguiar's microfiber cutting pad/disc? Might as well try for what might be most effective. What the heck, this isn't "rocket science", is it?

Do you have some sort of orange pad? If not I would start with a polishing pad rather than that maroon pad.

Thanks for the suggestion. It may take a week to find that orange pad. I haven't used it for a while....no reason to.

Well, you know Mike always discouraged the use of that maroon pad back when he worked for Meguiar's...or do you have one of the new 2.0 pads?
