Spotting in repairs

OJ'd, if it's a solid red chances are you're seeing shrinkage and it won't affect the color-if it can't be sanded and buffed out you should be able to just scuff the whole panel and reclear it then sand and buff. Metalics and pearls are a different story-any shrinkage under the base will be highlighted by the metalics.
 
Trying to look at some old threads.

We were originally just going to fix a rocker area and quarter panel on a small blazer. We scuffed the entire quarter, figure we spray that with the red then clear the entire quarter since there are easy break lines to mask to. But if you are just repairing the bottom of a door, do you still clear the entire panel or scuff the factory clear down and then attempt to buff it out after clearing the fresh base area.

Its the simple thing of getting a 500.00 truck that had rusted brake and fuel lines to use for the winter truck. So we have some time to weld in the required patches of the rusted thru areas, but are debating to leave the door alone with rust or knock that off, there is just alot of area to reclear the entire door.
 
Never ends well unless you clear the,'panel' and then,
You have a difference in gloss of said panel.
500 dollar truck and a 500 dollar repair.
You choose.....
 
This looked like a good place to post a question I have.
I need to repair a paint screw up on my '69 GTO convertible project.
I noticed a low spot I missed on left front fender after I cleared it. I just plain missed it when I was blocking out the primer. I could see it after clearing but decided to see if I could live with it after getting the car assembled and the fender polished out. I just polished out that area only for a test and I quickly decided I could not live with it.
Here's what I've got now after blocking it out with 320 grit on a long sanding block using guide coat.

The low spot is gone but as you can see, I've gone through the clear, base coat and have exposed red epoxy primer. The clear is Universal and the base is SPI Dark Red.
My plan is to spot spray a couple of coats of red epoxy primer about a square foot in size over that area, re-block and then one more primer coat with a very light blocking afterwards. This clear is probably fully cured. I sprayed it 10 months back. I know I will need to re-clear the entire fender but my question is about the base coat.
Should I just spot in base over that corrected area or should I re-base the entire fender?

I would prime that area before I did anything else. Spray base over that, it will show at some point. Plus the low spot will probably still show as well. Prime it, block it out. then blend that area.
 
Absolutely. That was my intention as the first thing to do. Prime the area and re-block. I thought I should even do it a second time.
But my question was about after that. I wasn't sure if it would be better to base the entire fender or just over the primered area. Sounds like you are saying I only need to apply base over the primered area.
