Best 'marker' ever....
I have been making things for a living for many years and patterning has always come easily to me, so I've had every pen, pencil, and marker known. (to me)
I may have heard it here, but, damn, these 'paint markers' are absolutely essential. Keeping records is one thing - keeping them handy is another. What's handy is to mark the part. Four new shocks (strip of protective tape over) got it ...two spring filter changes on the Deere got it, and more to come. (Generator air filter in the pic)
I cannot figure how I got along all these years without knowing about these?
