sander and gun?

[lt_paintballer]

Ok I was wondering if u can use a hand sander that u sand wood with on a car or do u need a sander that was made for a car. Also has anyone ever painted there car with an electric spray gun? As for the sander its a black and decker and it fits in the palm of your hand if your wanting to know.

You can use the sander. You do have to get different sandpaper.

ok thanx anyone know about the spray gun?

Like a Wagner? I sprayed an old truck with one once. Used Tremclad on it. Runs like crazy because I had to thin the tremclad so much. If you just want a spray on it go for it, but I wouldn't do it

ok thanx i was just wondering if anyone had ever done it.

Depends on what you're expecting out of the sander. You really should use an orbital sander (da) & lol, sorry, if you have to ask about the spray gun don't even think of painting your own car. Electric spary guns don't even come close to the atomization level of a correct airgun. Keep the wagner powersprayer for painting your house/ not your car.:;)

^what he said......We have a Wagner PowerSprayer and it didn't paint the garage very well at all.Don't know how they sold if they don't paint very well,might as well save and buy a paint gun and use that to paint things,much better spray and easier to work with IMO.

ok i wasnt gonna paint my car with it i was just wondering also what size air compressore do you guys use for painting a car i have like a 2 hp one i know it will take about a day to paint a car with that or am i wrong?

[JoeyK]

Depending on what type of spray gun you use, you'll need a compressor that'll put out atleast 45lbs continuous pressure on up to 65. (My Sata's need 45, older non-hvlp cup guns need 65 on average) A 2hp compressor is way too small. You can't take all day painting, depending on your paint it will most likely not have a pot life of more than 2 hours & will start to dry w/in 20 min of being sprayed( & in most cases faster, I mix mine to kick w/in 2 min or less). If you paint too slow it'll look very, very nasty. You'd have dry lines & blotches everywhere.

so would a 10 hp compressor work i think the gun i have is a cambell or somthing like got it at walmart for like 50 bucks.

[JoeyK]

A 10 may work, depends on the air volume output. What will happen if it's not strong enough is you'll run out of air, of course, but as the pressure drops your gunn will sputtter leaving nasty dry blotches & globs of excess paint everywhere that can turn to runs real quick. Then, as your waiting for the compressor to build back up your paint on the car is drying & when you start again you'll have a dry line. As for your wal mart gun, it may work but I doubt it will give you a quality finish.
If you've never painted before I really suggest you don't tackle this yourself. If you have a friend or relative that has you're better off going that route. Painting something small is one thing but painting something large, like a car takes alot of experience to get it right, or even in the ballpark/ close to right. I've been painting since high school & even I still have my bad days from time to time or something goes wrong. Believe me, you can't just decide one day "I think I will paint my own car" if you've never done it before. There are so, so many variables when painting something large & it only gets harder when doing it in a garage, etc. instead of a downdraft bake booth. You have to take into effect temp, humidity, & choose from 3 diff slovents & 3 diff hardeners to suit the conditions, then it will effect the charicteristics of the paint & how it goes on & the if it's a metalic job, well it can end up being a total nightmare for even rookies.
I'm not trying to sound like a jerk, I'm juts laying it all out there because from looking at your profile, it looks like you have a nice car. If it were a 2 or 3 hundred $ junker I'd say "Sure, what the hell give it a try & see" There's just way, way too many people out there that think it "can't be that hard" & they couldn't be any further than the truth. & I'm not trying to sound like superman either. Heck, even I'll admit I have days where things bite me in the a$$ while painting & I've been doing it for quite some time. Painting is like a game alsmost, becuase of all those variables, & cannot be played by the inexperienced & won.

see thats what i have i got a 93 cavi that i got for 100 bucks and thats what i want to learn on i bout it to learn to do body work as for family well i know more bout cars than any of them and thats not sayin much. Im also lookin at gettin a better gun. any suggestions with out spends over 300 or so. Wish i could get a Sata K3 but hey gotta start small. Also is there any vidoes or books that your know of are any good. One last thing you seem to be the man to talk to about painting im not sure were mentor is in ohio is that in the north or south i live by dayton and cinci. I want to learn and I know its not easy to paint thats y I want to know as much as I can. As far as school I dont have time to go and learn but if u know any in ohio please let me know. thanx man

[lt_paintballer]

also what size tank do u use with your compressor would like a 10 gallon with a 5hp work or are we talkin like a 10hp with a 50 gallion tank. I assume the bigger the tank the more air it hold so could u use like a 2hp with like a 10 or 20 gallon tank or is that just stupid of me to say and if so im sorry im so new to this.

[92CamaroRS]

you need to look at the facts of the compressor. it needs to be able to maintain 90 PSI at.......um......damnit i cant remember how much cfm.

Mmmmm, Sata's are nice guns. We have a Sata gravity fed cup gun at work but I have yet to spray with it. I generally use a DeVilbiss HVLP pressure pot gun for priming, and a DeVilbiss HVLP siphon cup gun for wash primer. For spraying paint I either use a DeVilbiss gravity fed HVLP cup gun, or a Randsburg electrostatic gun.

I agree spraying isn't something you typically just pick up. Very few people can paint their car with no prior experiance and have it come out looking great.

There are so many factors to think about. First off, body work. Bad body work will show though the paint. Mixing the paint, how much activator, thinner, and what kinds to use. The tempature and humidity. If you have a booth, if it's tempature controled or not. How much paint, how wide your pattern is and your overlap, also how much paint your laying down. Then you have drying, air drying or doing it in an oven and for how long.

And those are just a few of the basics.

Just a word of advise, spending a few extra bucks on a gun is worth it. Cheep guns are made with cheep parts like plastic internals. Where as you'll find the more expensive guns use nice machined aluminum parts that are more precise and last longer.

Do your home work, goto a bookstore or library and check out some custom painting books for tips and trick to help you out. then with all your new found knowledge take a shot at it. :)
