First of all, I have to say thanks to vxrmarc for posting his collection! Where can I find this bottle in the states??? Thanks !
Most garden centers sell that spray bottle..even the dollar stores have it...Wal mart has it in the outdoor section... AL
I got mine for extra cheap at harbor freight, I think it was 5 bucks, looks like the exact same one, from what I can tell
then on at Big Lots is not that great. It's not heavy duty. this is the one I've got - 2 quart size, $22 - Top of the Line Auto Detailing Supplies in USA. Or I seen another good one at local Napa, smaller (1 quart), but it was expensive - $60...made in Germany....
it is plastic, but the bottle itself is better. You can build more pressure with heavy duty bottle, and you can't do that with a garden sprayer.
