Was told by cashier last week if buy the extra warranty for $5. You can bring back for any reason and gat another even if bringing back 5 dirty ones at same time. Hell can not clean the thing for $5. Not sure how well would work on better guns but with cheapy for primer or whole deal if perfect finish os not huge concern.

Tested this last week with 3 dirty $30 guns. 3 new ones $15 bucks out the door.

How long is the warranty? Sounds like the same plan some have professed for spark plug wires at local auto suppliers.

I think 3 years when poay $5 at checkout. I have three each of $16 and $30 guns. Mainly because of tip size and one comes with regulator and gauge.
