Paint blending?
Okay so my car is about to go into a body shop to get the quarter panel and rear bumper replaced. I think the shop wants to blend, is there any reason why i shouldn't want this, why are a lot of people against blending if it creates no visible color difference between panels? This is being covered by insurance.

i figured a color like jet stream blue would fall into that category, i just always hear people not wanting a blended panel, i wonder if its more of a cost issue or what? I want my panels to match perfectly to to the rest of the car

Blending is done all the time on "normal" cars, but there are probably 95% of the people on this forum that will tell you not to let them blend and if that is what they want to do, then it must be a junk shop and you should get out of there. These comments are made by people who know next to nothing about paint.
There is nothing wrong with blending. If some other panel needs to be replaced in the future, they will just blend again and you will still not notice any difference. Get your car fixed and spend your time back on the road!

btw when they blend, do they usually sand the panel that is getting blended into and shoot a clearcoat over the whole thing?
so for a bumper and quarter panel replacement they would probably blend into the hatch, door on the side of the new panel and the non replaced quarter panel?

Yes JSB falls into that category since it is a metallic with a tintcoat. As a painter, I prefer to spend the time on the color match whenever possible to avoid having to paint another panel. I'd rather have factory paint unless repainting is absolutely necessary. Color matching is becoming a lost art, and blending is now pretty much standard procedure. When a repair or panel replacement requires repaint up to the edge of a panel, blending is almost mandatory with certain colors (exceptions would be solid colors like my Arctic White I can color-match that without blending.). Done properly, there is nothing wrong with a blended panel. Blending into a panel requires a combination of light colorsanding, buffing, and chemical prep. The color is blended onto the panel to achieve an undetectable transition, then the entire panel, regardless of how little the blend is, is clearcoated.

You can blend clear but on the corvette its much easier just to re-clear the whole panel. None of them are that big anyways.The only thing I would be worried is when they wetsand the newly cleared area. Believe it or not they might do to good of a job and make it to smooth. Factory corvette panels are loaded in orange peel. A trained eye will pick up on the fact that the newly painted panels are a lot smoother than the factory panels. The only way around this would be to have them wetsand and buff the whole car. If you ask me the whole car would benefit from that.
The orange peel left in the paint from the factory kind of annoys me.

The first thing I'd do, is make sure I only take my car to a shop that has a computer scan paint match system. The color and metallic match is an absolute clone of what's already on the car, with none of the variances some factory pack paint's might have. It's an expensive system and most shop's dont have one. Most shops that make the investment actually find these systems to save money, as nobody ever come's back complaining.

The paint in the paint shop at Bowling Green can vary somewhat from batch to batch. Without blending, it would be difficult to match since the color, tint, pressure, distance, velocity, angle of spay, thickness, metallic content and metallic particle size and the orentation of the metalic particles can affect the overall appearance of the respray. Not to mention the affect of the ultraviolet radiation from the sun on the OEM paint. Blending can hide small differences in paint appearance from the OEM paint to the respray.

one more question, if i bought panels off a jsb car are chances that these are a perfect match or no, do you think the color gm uses for JSB for example changes shades? For example, i can get a used jsb rear bumper for 400 or a yellow one for 150 but if the used jsb is off in color then there really is no point to spend the extra 250, thanks for everyones help
i am actually concerned about the orange peel as well, i feel almost dumb telling a shop to try to create orange peel so it matches the rest of the car...i dont think insurance will cover sanding and buffing the entire car

Now certainly starting with a color as close to factory as you can get it is the place to start, but application has more to do with it than anything. You can have a paint color that matches dead on per some computer printout, but if your spray gun parameters are all wrong, you will end up with a different color.
Parameters being, fluid delivery, atomization air pressure, fan pressure, target distance, pattern overlap, air temp and so on.

You can have a perfect color match in the can, but an inexperienced painter can make it look like two totally differnt colors. Getting the metallic and tones to match is up to the painter. Proper reduction, airpressure and spraying technique are part of color matching.

No way it means that. This is my point from my post above - another person that does not know how to paint.

Are you a body guy or have experience working in a body shop? Both of your posts were pretty dead on to what I was going to say haha.

Swiftrider has it right here folks. You can do all the paint mixing and matching you want and at the end of the day what is said above is what makes the difference. Computer scan systems are not perfect.
