Paint correction gone wrong!

Trying to help a buddy out with his SC and I think I’ve ended up doing more harm than good. I’m sick about what I just did and looking for some guidance to make it look presentable again.

Silver car, with an almost white film on the paint in areas, deep cracks in most areas that almost look like deep scratches.
I started by wet sanding the hood with 1500 grit and then polishing it out. Worked great and looks night and day better.

Feeling confident I moved to the fender. The paint here appeared to be broken, almost like when it was still wet someone sprayed water on it. The paint looked to be separated if that makes sense? I started on the fender with 1500 with very light pressure. The top layer of paint seemed to come off exposing light bright silver underneath that polished out shiny.

Here is where I screwed up, while sanding in one area I quickly got to what appears to be grey primer. So now I have a mess on my hands. I’ve put down the 1500 and not sure where to go from here and how to fix what I’ve done.

So couple questions for my Friday night Pelican groupies.

Did I burn through the paint?

Did Porsche use a primer on a 76 SC?

Would original Silver paint darken with age?

What if anything would you suggest to fix my screw up?

*also if it helps i believe the car is a 79, we also think the hood has been resprayed but not sure if this fender has.





The sand paper on the left is the exact area that is messed up.

Sometimes during a partial respray, paint is fogged or blended over other areas of the car to help the match. It may be the case that you have found such an area.

You can't fix this without paint.

The fogged/blended paint makes complete sense. If a paint shop did that would they have sanded down the paint before spraying? Maybe that is why it was so thin in the area I went through.

Have to admit I would never have thought of that...so points for ingenuity...

Yes, sorry to the OP, but I think you've stumbled into a area thats seen previous work, and it will probably need fresh paint. It's not reeeaaallly your fault, often those blended areas don't age well, and it's just a matter of time. You just hastened the 'critical moment'. (Sorry!)

A good painter will be able to match the existing weathered paint..

Shame about the silver,easy repair but the colour match is the killer here,I suspect blended paint but if the panel was resprayed and insufficient clearcoat thats the end result also.

That guy has it down pat. No expenses, no overspray, no fancy heated booth, no EPA, no clean up, no overhead.....

You have ripped the clear on a previous repair " stop wasting time
There is no fix. Prep the front panels and drop it off at a shop and be done with it.

Without real skill and material you have less than no chance of blending that silver in
In a garage hack paint. No biggie it happens . Silver without modeling is much harder to
Spray than you think.

And for heavens sake remove the headlamp trim and mask the jambs if your gonna
Color sand and polish.

Unfortunately, dropping the panels off and having them painted without the rest of the car present will almost certainly mean that even the casual observer will be able to tell that they've been re-painted. After all, the very thing - blending - that caused the issue the OP is facing is necessary when dealing with pretty much every color except black.

Silver is one of the most difficult colors to match too. I'd definitely let an expert take it from here. He will use a camera to color match the worn paint on the same panel to create what is effectively a "custom color" that matches what is on the car.

A professional will be required to fix this...

I'd think your friend realized the risk he was taking when he allowed you to colorsand his old paint. Hopefully your friend is not angry with you. Perhaps you guys can split the cost to have the panel matched.

As for the YOUTUBE video... I can't believe i actually bought three professional spray guns and a compressor... lol

I don't need no stink'n compressor... lol

It actually didn't look bad.
