problems with finding defects

[pampos]

Hi guys,
i noticed sometimes that some defects are not visible during the day but only in night...
in my shop a lot of daylight is coming through the windows and this is i guess is making my halogen lights ''weaker'' that they should be.If the day is cloudy or the sun is gone or even at night, i can see everything under the light...
this is a big problem if you consider that you see a perfect finish but you will find out later that it is not...For example there is a car in the shop for service(not for polishing), and during the day i saw that it was full of some light swirls.When i saw it in the night,with the shop lamps, without any daylight, i noticed that the paint was full of holograms rids and swirls....
I thought that i should detail the cars during the night but it is almost impossible
Also I am thinking to create a 'dark room' in my shop with a tent...Is this a good idea?
what do you think?Any other suggestions?

Re: problems with finding defects

If a dark room, or at least a shade for the windows is what you need, then do it.

Not sure if something like the "Swirlfinder" light would help you. It is a Brinkman Dual Xenon light. There is probably something similar there, being able to hold it closer to the surface could help?

I tried also the Brinkman but it doesn't make any difference at all....Only when it is dark all the ''swirlfinder lights' work great....In the daylight i guess they are hiding a lot of defects especially the tiny ones....
