I'm good with a spray can.... what am i doing wrong!

hi guys.... i seem to get better results with a spray can than i do with a Spray gun....

I've got a el cheapo spray gun... and it seems to orange peel..... I'm not shure how much paint to spray on at a time....

when i Spray can... i just put ultra light coats... like 5 times.....

but i think that i'm spraying too little at a time with my spray gun.... I'm spraying at 40psi... and mixing it according to the directions on the can of Nason...

How thick a coat am i supposed to spray? i think i might have moved the gun back and forth too much...... because when i watch american hot rod.... they seem to move much slower.... so i'm assuming it should be a relativley thick coat.........

Sorry i'm just fumbling my way thru this body work thing...

this is the cheap gun i have

I have one of those guns and it works great. Sounds from your description that you are not putting on enough material in a pass. First coat can be the mist coat to form a tooth for the rest of the job but subsequent coats should go on looking wet and be overlapped 50% for uniform coverage. Only way to describe it is get uniform coverage as heavy as possible without causing runs. This can only be done with proper settings and proper technique. Spray guns are light years ahead of rattle cans in capabilities but bring with them a higher level of complexity and skill set.

You just need to experiment with paint and air settings and painting technique to get it right. Get an old fender or some such practice pallet and play with it.

Seconds per foot for topcoat/clearcoat:

The speed of a pass to consider or "work from" might be to actualy count seconds that the gun moves per foot. An example; on a 4 foot wide door starting the gun off the panel at about 8 inches from the surface with "happy" presure/settings count 1 mississippi 2 mississippi 3 mississippi 4 mississippi etc..every 12 inches ... This will give you a sence of how to slow your passes down and really slam the material on there with a bench mark to set your stlye to depending on how long it takes to say Mississippi.

Of course color coats for BC/CC systems are "dusted on" since the goal is color coverage/management not final gloss as with clears or single stage paint.

hope to have helped.

Hold the gun the other way and you might get a better feel of control also. The small tab sticking down goes in the crook of your hand and your index finger goes on the lever. Of course the gun is for a right hander. It might give you that "spray can feel of control". Try thinning down the paint a little more, back off the pressure to around 30psi , and adjust the fan spray. Keep us informed how it turns out. BTW here is the info you forgot to post with the pic. PSI is calling for 30 lbs. And it is a touch up gun. Definately not for squirting anything big.

Now you can do professional custom spray painting, detailing and touch-up with this lightweight spray gun. Right-or left-hand control. Self-centering brass air nozzle lets you change spray pattern from flat to round. Covers an 8in. area from 8in. away. Siphon feed cup has an 8 ounce capacity. 2.8 CFM at 30 PSI, 4.0 CFM at 50 PSI. 1/4in. NPT fluid and air inlets.

What are you painting with that gun....it's a touchup gun.

If you want to do a whole paint job, you need a bigger gun.

And you partially solved your own problem....you bought a "cheapo" gun....you get what you pay for.

yah.... I was a afriad of getting a run..... so i didn't want to spray too much on..... I was defiantly going way to fast......

So aparantly i should almost spend 4 seconds per foot? is that correct... i know it's not exactly 4 for every app..... but i was like 4 feet in 1 second.... i was so afraid i was going to get a run, or have 1/4 inch of paint on there.....

so it's NOTHING like spray painting with a can..... one mist coat.... then COATER ON LIKE NO tomorrow.......

I basically ended up doing 6 passes on the same door in like 20 seconds.....


Man i need to go get a job at a body shop so i can learn all this stuff... it seems like there is so much to know.

I'm just painting the bottom half of my doors on my 96 Golf.... Because i want to sell it, and i figure cleaning up the rust spots before i do is a good idea.

but i plan on painting a whole car next month.... if this goes well..... so you don't think i can use my cheesy gun to paint a whole car?

C'mon..if you watch 'em on TV paint a car then you know you need a bigger gun. Besides that when you bought the touch up gun it states for use of detailing and tough up. Not shooting something the size of doors. unless it is the bottom inch or so.

GOTCHA





this touch up thing is getting a little confusing..... whats the difference..... if you paint 4 inches wide 20inches wide....the paint is still going to look the same in a 4 inch spot as a 20 inc spot..... unless what they are saying by touchup is.... dont use this where your going to look at it everyday..... ???
dunno... I know it's a poop gun, but i didn't want to go pay 200.00 for a gun to find out i'm a absolute loser at painting......
grrr.... maybe i'll see if i can borrow a real paint gun from somone..

If you don't want to spend a lot on a gun, you can always try the HVLP gravity feed gun at Harbor Freight for about $40. I've got one and it works great.

Painting 4 inch wide strips will make it look like a zebra.lower the pressure. and spray at least a 8-10 strep on each pass. You will have to stop and fill that touch up gun after a few passes, then you will have more dry places. Napa used to have a cheapo gun that worked good enough to paint several cars.

You have a fan adj. and a quantity adj.

You should have gotten some instructions with the gun.

The larger spray guns have much better adjustabiliy than the touch up gun, and is therefore going to lay down a better coat of paint.....

You are definately spraying much too light. Painting is an art, the best jobs seem to be just on the edge of dissaster (runs)
