Using a Cornell paint pen question

[ramonesfreak]

I picked up one of these paint pens and the instructions say to thin the paint to an ink-like consistency. I’m assuming I get some paint thinner and add a few drops to a small amount of paint and then stir and repeat if needed until consistency is ink-like

Any tips from those who have done this? In the past I have always just used a fine artist brush without thinning the paint but have never been happy with the results

i have a few they work ok on chips not as good on a scratch.
just thin the paint the same way you do to spray it out of a spray gun.

Toothpicks work very well and cheap.
