imgur: the simple image sharer

I was told that gray blob is prime. This is after a really bad first time attempt to fix a deep key scratch that went down to the metal. I was told I now need a paint job. How much does that usually cost? No way to fix this on my own?

Hard to say from just looking at a pic, but it doesn't appear to be a strike through. Could you circle the subject in question? Maybe get a little closer shot?


What did you do use something crazy like an 800 grit sanding disk?
 
For future reference, you can't fix a scratch that's down to the metal by sanding, because in order to get down to the level of the scratch you'd have to sand all the paint off. Any scratches that are down to primer or metal have to be filled with touchup paint. You can then try to sand the touchup paint back down to the level of the clear and polish.

There isn't a good recovery from what you've got now other than to have the panel resprayed at a cost of several hundred dollars. Or if you are really good with a spraycan you could try to spray color and 1K or 2K clear yourself.

Here's another shot: imgur: the simple image sharer

I got keyed down to the metal and I filled it with touch up paint, sanded 1000>2000>2500, DA compounded, polished and waxed it because I didn't want to go any further.

That thing is like above the scratch too..

Thanks for the info. That's what I did. It's just that I still sanded too much probably. Is this clear coat failure or primer?

It was operator failure, to understand what he was doing before he started sanding the car. Clearcoat failure is caused by environmental exposure, possibly accelerated by over-polishing. What you have created is mechanical damage by removing paint. You've removed the clearcoat, and removed the color coat.

It's time to fess up to whoever the car belongs to. You can just leave it the way it is if it's not too noticeable, it will probably take years to rust, depending on your locale. Or you could layer some touchup on it, although it won't be smooth.
 
Hope it's not a customers car? If it is please tell me you have insurance or have the cash to pay to get it fixed.

I apologize, I somehow missed this post and the additional picture. In that pic it looks like you thinned the clear. It's always best to use a block when you are trying to level touchup blobs, and to mask the surrounding area with tape. Of course Langka or Dr. Colorchip is also good, or you can do-it-yourself Langka with some lacquer thinner and a cloth, paper towel, etc.

Again, sorry for my earlier post, you did the right thing, it looks like you just overdid it. That's why I hate filling chips etc. because I'm always afraid that's going to happen to me.

Here's how it looked before

A week after I detail my car, this happens.. - Imgur

That last pictures tells a pretty telling tale. You can almost see where you sanded through the clear. Then inside of that 'circle' you can see where you sanded through the base and in that 'circle' you can see the primer.

You went to aggresive. I've always sanded my touchup jobs with 2000 grit ONLY!

Around $300 per panel if you know someone (that's good). You should really invest some time establishing a relationship with a painter before ever getting started with wetsanding projects

You should remind dude this thing was scratched. Hopefully he will chip in some cash
 
Thanks for all the help guys. As a paint job may be pretty pricey right now and with the pictures I've provided to be sure, what's a temporary fix now? I already threw on compound polish and wax..
 
there is no temporary fix.. if you were close to me i could respray the panel for cheap, however you would need to get your own paint that is already color matched.
A shop is going to charge around $500 to respray.
