I own a couple SP Systems backpacks. I recently went to retrieve one from my trailer rack, and the wand was missing. I suppose I let it get loose, and it flew out somewhere on the road. I FINALLY found an online retailer that sold the replacement wands, and I ordered a brass wand to replace it (another question just came to mind). It arrived, today....but, the tip/nozzle part that's adjustable isn't part of the replacement. So, I'm still out of commission (with this sprayer). 1. I need a replacement for this to get it back in action. Any recommendations on a part/retailer? 2. Are there BP sprayer tips that are better than others? I'm assuming it depends on the task at hand. I use this sprayer ONLY for gly.. But, I have a coupel more that'll see some selective postM apps.. RE: the brass wand.... Why is (if, indeed it is) brass a better choice for this (BP Sprayer) application? Easier to clean/keep clean? No idea, really. Thanks.
