can clear darken base coat?

[stshoo]

I had my door touched up about early last summer after my car got hit by a shopping cart. I know when they had the car they had issues with getting the color right, but it seemed like they had it figured out and the car looked good. They ended up blending the door into the front fender and cleared the fender and door. Recently I've been noticing that the door is darker than than the rear fender (factory paint).

I haven't noticed a difference on the blended front fender, but there is so little surface of it next to the hood (hood also has xpel on it) that I don't think it would really be noticeable. But under most light and angles, the door/front of car on the side is darker than the rear and the lower sill panel.

Is this a possible issue with the clear? The car was coated and although I'm in FL, it's been garaged alot. I'm concerned that the UV is yellowing or darkening the new clear. Anyone have experience with this on any newer vehicle? It was done by the Ford dealer which is a certified Ford shop. I ended up paying out of pocket for this since the store wouldn't take any liability and it wasn't significantly more than my deductible. Thoughts?

I have not seen the clear coat darkening before, and I did have a couple of cars painted for me before... I can only assume that either a low quality clear coat was used which has started to darken, or they did not get the color matched properly, and it became more visible after it dried out ... paint still works several days if it is not the top shelf paint, which cures almost instantly...

I would go back and just ask them, see what they say.
Good luck

Depending on the quality of finish used, or the composition of the product (Waterbase compared to Solvent based) You could be experiencing a yellow or muddy type clear job.
It also depends on if they had to lay primer or anything down. What color is the car?

What color is the car?

Avalanche. I tried paintless dent and it was still wavy there, hence why I took it to the next step of paint. My guess is they had to prime the repair spot at least. The door and the front fender look fine especially with the door open, but as soon as it's closed next to the rear fender, the darkness becomes evident.

From the factory that car was probably sealed with a white sealer that gave the gray some life. When it was repaired, it was most likely sealed with a darker, gray sealer with causes the basecoat to react differently and not match the other colors. That's my best guess, or someone is just terrible at paint matching.

[MENTION=11090]Livernois Motorsports[/MENTION], excellent point about the difference in sealer colors. I hadn't thought of that. The technology used in the paint matching field these days is spot-on (see what I did there?), so I would be very surprised if the base was the issue - IF quality waterborne technology was used. If a cheap clear was used I could see some yellowing, but this would be down the road.
