[demonds]

I just got a brinkmann dual xennon to try to spot the swirls on my white car and I cant seem to get it right. I can do it on my wife black car and on any other color but what is the deal with the white??? Could you guys give me a few tips for white paint??? is not finding the swirls my problem but finding them on a white car is. Advice from any members with same color car will be highly appreciated. Thanks

Nature of the beast. Darker colors provide greater contrast so when the light hits the clearcoat, the refraction is much sharper than a white or silver paint finish. Plus side, it's harder to see swirls in light paint. Minus side, rest assured the swirls are still there, and being harder to see them makes it much more difficult to verify their removal.

Put the car under dim lights (Incandescent light) and look at it at an angle.

Interesting thread as I too just bought this device.

I was unable to find any swirls on my mothers car which is a light aqua greenish color, but my car shows a ton and it's a dark blue.

Then again, her car is an '07/'08 and mine is an '03

Exactly. I have a White car and what has worked the best is either indirect sun light (my car in the garage on daytime) or my garage lighting.
For either way I have to find just the right angle (takes a few tries) to spot the swirls and scratches.

See this link on paint pigment on page 13. http://www.howeverythingworks.org/supplements/paint.pdf

Here is sample quote taken from the docuement: "For example, under red
illumination blue and black paint both appear black but under white illumination
they look different. Similarly, two paints that look identical in incandescent lighting
will look somewhat different in fluorescent lighting. This behavior is called
metamerism and can only be avoided by using exactly the same pigments in the
two paints being matched. If you can't match the paints chemically, you must do
the color matching in the proper lighting. However, metamerism is occasionally
helpful, such as in reading faded old letters. In the proper illumination, the contrast
between the ink and the paper may be greatly enhanced."

On the few white cars I have done. I find that when using the Brinkmann, you have to shine it on the paint in every conceivable angle. You will find them. They nare there. It is just a harder process to find them.

I never thought about the color of the light being used to help see swirls and scratches.

So uh, black light/ultraviolet light on a white car would show the swirls easily then eh?
