It's about time! The first ACID RESISTANT SPRAYER! Wheel acid eats sprayers, as we all know, but finally, someone has manufactured a sprayer that is designed to last signifcantly longer when used with wheel acid! Field tests show the proprietary design results in unsurpassed acid resistance. Also 40% more output per stroke reduces the number of times you have to pull the trigger, making for a quicker cleaning job. Not to be used with solvent based products- keep only for your wheel cleaner! It's simple math: would you pay twice as much for a sprayer than lasts 10 times (or more) as long?
