Funny thing happened when I was touching up some chips. Mellow Yellow tends to change shades depending on the light. Sometimes it is dark and sometimes it looks lighter. When I did the chips, they disappeared and you had to look hard to find them. When the light changed, they didn't and you could see them with no trouble. Oh well, I'll keep it in the correct light at MOTD and nobody will notice. Jim
I've never been able to make an invisible touch up with any paint pen. It is close & looks better than all those primer spots. As my good friend used to say it's good enough for whozits for....
The nature of touchup repair is that the paints rarely match...even the factory paints. Metallics never match due to the metallic flake laying differently than the sprayed on flake so it always looks darker. I invested in a touchup system called Applied Colors..costs $1,200 but I can match any color. But once the color is matched, laying the color down takes technique. Paint pens and touchup brushes leave a blob. Products like Langka can smooth the blob, but you still end up with a smooth blob. Dr. Color Chip helps you remove excess paint after you smear it into chips, but the chips don't truly get filled...it's not much different than using a Sharpie and coloring the chips in. Paint pens allow precise blobs. My point for this post is that, short of respraying a panel, any type of touchup repair, whether you spend a lot of money or a little will yield varying amounts of success. My system enables me to make repairs that are invisible from one foot away without blobs and without mismatched color, but they are still visible from certain distances and angles. Richard
Dr Color chip matches pretty well to my space blue but like you say, it is not perfect. But it is easy to use and a marked improvement over an untouched chip...
