Alright, so today I'm gonna walk you through my little project: building a DIY vehicle washing gun. I'm no pro, just a guy who likes to tinker and hates paying for car washes.

First things first, I grabbed my tools. You know, the usual suspect: a drill, some screwdrivers, pliers, and a utility knife. Oh, and don't forget the safety glasses! Gotta protect those peepers.

Then came the parts hunt. I rummaged through my garage and found a garden sprayer nozzle – the kind you use for spraying weeds. That was going to be the business end of the gun. After that I got a hose connector, a trigger handle from an old spray bottle(lucky find) and a bit of PVC pipe.

Okay, time to get my hands dirty. The initial step was attaching the hose connector to one end of the PVC pipe. I had to use some sealant to make sure it was water-tight. No one wants a leaky washing gun!

Next, I had to modify the trigger handle. I cut off the original spray tip and carefully attached the garden sprayer nozzle to it, using epoxy to hold it in place. This part was a bit fiddly, but I got there eventually. Make sure the nozzle is pointing in the right direction, or you'll be washing your feet instead of your car!

Then, I linked the trigger handle assembly to the other end of the PVC pipe. I had to make sure everything was aligned correctly. It's not rocket science, but it does take a bit of patience.

After that came testing time. I hooked up the hose, crossed my fingers, and squeezed the trigger. To my surprise it worked!! There weren't too many leaks, and the spray pattern was pretty decent.

I used my makeshift vehicle washing gun to clean my car. It actually worked better than I expected! It’s not a fancy pressure washer or anything, but it got the job done, and I saved myself a few bucks. Plus, I had fun building it.

Lessons Learned:

• Sealant is your friend. Don't skimp on it, or you'll end up with a soggy mess.
• Take your time. Rushing things will only lead to mistakes.
• Don't be afraid to experiment. If something doesn't work, try a different approach.

So, there you have it – my DIY vehicle washing gun project. It's simple, it's cheap, and it works (sort of). Give it a try if you're bored and want to save some money. Just don't blame me if you end up getting soaked!
