Well Jeff.....
This is my take on the gig and what I do when a scratch happens to one of my rides. Brush type touch-up paint have been around for a long, long time, and works great (at least for myself) with the brush type you can fill in big scratches that require layers of paint to be built back up to the original finish.
With a pin type touch-up you have a lot more controll filling in light,thin scratches where the depth is not that deep and lots of layers of paint are not needed.
I have filled in some big scratches in the past on my rides, it takes some patience when they are deep due to the multible layers of paint and waiting for them to dry before you throw down another layer.There are times I will wipe up the excess paint around the scratch(s) with thinner and a rag to save on sanding time once I have the scratch built back up to the original paint surface.
Now a days there are all kinds of very fine sandpaper, ie from a 1000 up to 2000 & 2500 grit. Once you have the surface the way you like it, you can throw on a peice of this ultra fine paper on a sanding block and sand the paint surface smooth till where no one could tell if there was a scratch at all. Then hit it with some polishing compound and your done. Don't forget to wax the ride also.
If your ride has been custom painted, don't forget to get any left over paint from the painter or at least the paint number/manufacture so you can buy some if needed down the line. I have used airbrushes in the past to do scratch touch-up work and have had vantastic results.
*REMEMBER* A factory painted SSR has been
CLEAR COATED so depending on the depth of the scratch you might need color touch-up paint along with the clear coat touch-up paint.
As always, BLACKIE
