Paint finish

That means it was in the original paint and you removed enough mils of clear for it to come out. It's going to be a different shade without the clearcoat. The clear doesn't "melt" into the color so try shooting some clear over that area. A little blendz-all after the clear and then polish. If there is not enough mil's of clear it will start lifting off/turning yellow around the edges.

 

Yes I have tried white vinegar it really did the trick on mine.

 

LOL. Easy to forget that someone has little/no experience. If i can do it why can't you. LOL

 

Check this out. If you're going to have to get it professionally sprayed anyway, it won't hurt to try this:



This guy shows you how to blend it right off the bat:

 

To do right you need to remove the clear. You can try to feather it back further and clear the whole section but will likely be able to see the transition. Urethane's are not easy to "melt" together like enamel/lacquer

 

The stains are happening because the base coat is flat ( matte) and dry. Wax will not help. You will never get it to shine. It is a basecoat/ clearcoat system. The red basecoat sprays on matte finish just for the color. The clear gives it the glass like depth and shine. The paint can be saved. It has to be color sanded clean and smooth and resprayed with a clear etching type gloss coat. The compound/polish and wax will just add foriegn oils that will make it difficult to clean out of it and make it worse looking and nothing clear will stick.

 

Also on basecoat/ clearcoat system the base color has no uv protection. The clear is what gives it that. Everytime you wash from now on after the clear peels off don’t be surprised if the sponge and water turn red. The paint becomes chalk rather quickly.
Just think of late 80’s early 90’s Gm’s that had the clear peel problem as an example.

Texas heat and sun is the devil on auto paint.
