Ok... I have tried a number of different off the shelf plastic spray
bottles. They all seem to fail in fairly short order. Some will work

if you (yuck!) suck on the nozzle for a second. Its like they lose their
prime and won't self prime again.

I have noticed that the pumps in the commercial products (rather than the
bottles bought as generics) seem to hold up better. I've got an old
Meguiers clean and shine product bottle that has had a dozen refills of
misc
gunk through it and it still works ok. Currently its filled with vinegar
and water for removing hard water and river gunk from my boat when I
bring
it back from the river.

The thing is I would like to be able to find a source for spray / squirt
bottles with pumps that will hold up. I need to spray various things from
oil to WD to cleaner and none of the pumps seem to last. I bought a
gallon
of WD and a bottle with their label on it about a month ago, and already
the
pump is experiencing lost prime and won't pump back up without a little
help. If I set it down for half an hour and pick it back up it will have
lost its prime.

Gack.

There's a wide variation in what's in the innards of those things(the
cheaper, the better, from the OEM standpoint), usually the check ball/
spring combination and the plunger seal are all selected to be inert
to the product they're pumping(but not always). Anything with acid in
it I would suspect would eat the check ball spring if it was intended
for petroleum products only and anything intended for water-base
products I would suspect wouldn't last very long pumping petroleum-
based stuff. I use the bottles that the stuff came in for refills
from gallons. Your WD40 sprayer, I presume, was a fine chink product
intended for something else but relabeled. For that sort of stuff I
have metal sprayers that can be pressurized with shop air or even a
bicycle pump.

Hmmm.... after reading your post I did a quick search. They can be quite
expensive can't they. ($30 -$100) I wonder for some media if it might not
be frugal to take a cheap paint sprayer and add a schrader valve in place of
an air fitting. Should hold up to paint, oil, and water based chemical.
Might not hold up to corrosives, or some caustic cleaners, but for most
other things it should be fine.

Harbor Freight used to sell these for about $10

Ive got a number of them that I use regularly for everything from WD40
to Acetone, to spray paint

The more you present a leftist with factual evidence
that is counter to his preconceived world view and the
more difficult it becomes for him to refute it without
