Happy Weekend folks !!!
I was today years old when I learned the caps on the CYA bottle and squirter bottle are interchangeable.

The pointy tip made it much easier to add the appropriate 50% of R-0013 instead of pouring too many glugs. Then, the cap meant I didn't have to put my finger over the hole on the squirter tip to shake the sample bottle.
You're still going to be trolled by the googley eye, but the first parts just got better at least.
