Marking ABS?

I have a difficult time seeing pencil marks on ABS, especially in the dim lighting in the crawl space under our house. Do the pro's use a some other type of marker, like a lumber crayon or soapstone?

A white or yellow paint pen works great.

Or what I do is to put my thumb on the lettering until I'm ready to cut it.
I haven't marked a pipe in some time.

Same with copper. Just put your thumb where the cut will be.

I will mark cast iron pipe. I don't like the chain wrapped around my thumb when I squeeze the handles together. Yellow or Red crayon.

I also use hand measurments whenever possible.
Width of hand,
Hand with thumb out,
three fingers
two fingers,
and whatever I can think of that works quickly.

I just "remember" where on the lettering I have to make the cut.

Yeah, you always get the last word in.
I put my thumb there to remind myself of where I'm supposed to remember it for.
Kind of like repeating someones name a few times.
Hey.......what the heck were we talking about?

Thanks guys. In this case, I'll be cutting a couple of sections out of an existing drain line and inserting a couple of combination wyes to accomodate the relocation of a toilet and shower. I already have the vents roughed-in, so I was trying to be fairly (overly?) precise with the alignment.

I have a silver paint pen for writing on computer disks, so I might give that a try.

You may find that if you are "overprecise" on the measurement to insert a fitting, that it will not go into place. That is one time where being a bit sloppy towards the "large" side can be a benefit. The problem with using your thumb is that the cutter is not always within arm's reach.
