Harbor Freight spray gun

-
When I'm done with a HF purple after a project I don't even bother cleaning it and return it with the receipt and get a new one to go on the pegboard.
I think I returned 3 or 4 last year using the previous return receipt.
They never ask why it's being returned.

Whats funny is how SPI states a 1.4 for epoxy but it works fine reduced some, high build needs 1.8 - 2.0 and I have never been able top shoot any polyester unless a 2.5! which I avoid!!!! I would be happy with a throw away 1.8-2.0 gun.

I have a Devilbiss primer gun with a 1.8 tip and a 2.2 tip. I use the 1.8 tip for urethane and epoxy primers. The 1.8 is great for urethane primers. Some use a 1.4 or 1.5 tip for epoxy primer, but I like the 1.8. You just have to adjust the pattern so it's not too fat/wet. I always use a 2.2 tip for high build polyester primer. I've tried a 1.8, but I don't like the pattern. I get a much better, wetter pattern with the 2.2 tip. A smoother wetter coat will have far less texture (orange peel), which will require far less sanding. Now you can thin high build polyester primers with about 5-10% Acetone (read the label). That would make it easier to shoot with a 1.8. I have sprayed epoxy and high build polyester hundreds of times, and I like the 1.8 or 2.2 tips. If you drill out a nozzle, don't guess. Get as CLOSE as possible to your desired 1.8, 2.0 or 2.2 mm tips. A 1/16" drill bit = 1.5875mm. At 25.4mm per inch, the formula is 25.4mm X 1/16 = 1.5875.
A 5/64" drill bit = 1.9844mm and a 3/32" drill bit = 2.3719mm.

I love flow charts. When I was in Market Risk Analysis at the Federal Home Loan Bank, one of my jobs was to complete flow charts for all of our processes. Some of them were 20 pages.

That is absolutely, 100% dishonest. That is the same as stealing.

You're Wrong, it's neither.
The manager himself told me about the return policy after he noticed me buying new ones every few months for a few years. I'll take advantage of it until the loophole is closed and any other for that matter.
You can also purchase the warranty and do the same if it makes you feel Holier than thou.

So Harbor Freight should loose out on a couple of hundred dollars of profit on the consumables most people buy when returning a $12 spray gun?
It's about getting customers in the door, Dummy. Who goes to HF for a return and doesn't buy anything else while you are there?
Think business.
 
I just laid down some 2K primer with the HF purple to me it didnt lay down as "heavy " as I would have liked but I am used to a siphon feed gun I figured that was the difference. I had the fluid adjustment maxed on it . It still did the job though and I just laid down 2 good coats.

Good info. I admit I have never used much polyester primer and it was so thick!
I have issues trying to use high build urethane primer unless I have a 2.2 so I will try the acetone!!!
I have 3 guns of old that were primer guns and I will soak one today and maybe revive it. I did find some 2 or better replacement tips in my junk also.

I have buds from ages ago that could do absolute flawless work with NO booth, no extreme high $ guns, etc., so when I don't measure up I know it is just ME!!!!
 

I have use 1.4 tipped Sharpe guns for epoxy, base and clear. And single stage, laqure
And bought this for thick primer like Evercost Slick Sand. Smooth filler primer matters. Just look at guys like Bad Chad, who thin out thick primers. It makes no sense to have rough primer that needs sanded down and a large part of what was used wasted.
Buy a 2.2-2.5 like Evercoat recommend. Less spayed on material is smooth l, fills and is blocked. It's simple math. Less material used. Less labor.
There are less expensive 2.5 than this one but has parts that rust in cheaper guns made of Stainless. Kinda a Buy Once Cry Once.
High-Performance PRO-33 Series HVLP Spray Gun with 2.5mm Tip, Air Pressure Regulator, MPS Cup Adapter
I do have a Purple HF I paid for. I have used the 1.4 on paint and sealers no problem. Every now and then my buddy calls and says his gun is messes up so loan him the purple and tell him keep it. It is normally an emergency. I don't want to loan my good guns.
He shoots mostly high end candy and pearls and does well.

^^^^ Thanks and I agree.
I am a decades long "duffer". Must be a slow learner or I would know more by now!'
Best advice amount other best advises are for a guy to read the tech sheets!! I understand guns can c=v ary but using their recommended lets say tips, gets a guy there.
I have had good results with the cheaper-ish TCP Global guns over the years. The one mentioned above is not a terribly high or either cheap gun, but should be one to take care of!
 
While we are getting off track I'll add a little. I have a 3M accuspray that I use for thicker products. The tips are disposable but I sometimes clean and reuse them but what I like is that I can drill the plastic tips to the point where they wont even seal on the needle. I spray bedliner products this way some times. It gives a much finer texture than the big old splatter guns that come with the kits. Kind of a custom feature for rockers or tailgates where the canopy has worn the paint off. Just make sure the first pull of the trigger is on the masking paper or you will get a big glob to start with. It comes with different sized tips and sprays pretty well.

sounds like a 'lifetime gaurantee " I used to exchange craftsman tape measures when I was a framing carpenter quite regularly but theyd break every 6 weeks

Good to know!
 
OK, guys, you have forced me into this. I am going to buy a purple HF gun and drill the nozzle out and spray some heavy primer.

True that. I do a combination of adjusting the pattern/fluid amount and thinning the high build primer with acetone. I have gone a little over their recommendations quite often to get a smooth coat. As you say, that results in less block sanding and less waste. I just allow a bit more time between coats.

That is ridiculous. That is the same as saying that if you steal some stuff from Walmart but buy some stuff while you are there, they should be glad that a customer came in the door. And name calling is highly inappropriate.
Bragging about stealing and then trying to justify it. Time to hit the ignore button!
