What do you guys use to see swirls ?

And also Cermaic coating on white/ silver cars
Someone did mention using a a light though a white colors board to see.

Answer 1:

Just use a white colored LED like a cellphone light. Yellow light is better for darker colored cars.
You can see the swirls no matter what color light though. Just play with the distance of the light and it’s easy to see.

Answer 2:

I use scangrip lights. Multi Temp is the key.
Don’t need a $1500 setup like mine dude. Just one light that goes from like 2000k up to 6000k in temps and you’ll be set.
