paint gun questions- spraying some paint and bondo

[expo5.0]

i am going to be really stepping up and doing a lot more glass work in the near future. i'd really like to start spraying bondo to speed up the sanding process.

what should i buy?

i'd like something i can use for other purposes too, but if i can get a really crappy gun that only will work for bondo thats fine too.

help me out, i'm new to the paint gun type thing.

Can you spray bondo??? I have never heard of this.

I am looking to buy a paint gun soon, but I am not sure if you are going to be painting or not.

You are a bit confused.
Bondo is a manufacture of body filler.
Neither of them can be sprayed.
( through a paint gun at least )

I don't know much about the paint aspects just the body work stuff. I do know this though a gravity feed gun is the only way to go.
Meaning the cup is on the top of the gun, not on the bottom.

Has anyone ever tried painted there X on there own, I was thinking if doing this to my crappy 91 explorer paint.
I'm just looking for some advice on how to do this, i not really picky, anything would be better than the disapearing clear coat and cracking going on, in my paint.

i ordered a 6 gallon 2 hp compressor, a psh3 gun, and a 6" da sander all from porter cable.

the air should really help out with the sanding.

your right the "bondo" name products can't be sprayed- sorry. however, you can buy polyester fillers that are made to be sprayed through a paint gun. they are around $50 a gallon or so if you get them off the net and that lasts a long long time (or so i've heard) and will cut sanding time on major projects by 50%.

i will let you know, since i'm doing my sub box, 5 doors, center console, rollpan, etc. etc. and the entire rear end of anotherh guys truck in the near future

that type of thing

My concern would be the air.
Since the spray is air induced it seems air pockets
( ie. pin holes ) would be pretty common.
Probabally not the best for finishing a body panel, but it could have other aplications I am sure.

I will say that 6 gal of air is not nearly enough to power a lot of air tools. A DA sander is the pneumatic tool that uses the most air, they are very air hungry. My DA causes my 30 gal compressor to run almost nonstop until I stop using it. I'm not sure how it will work with a paint gun, but you surely don't want to stop right in the middle of some paint work and wait for your compressor to refill.

yeah.. paint guns require high CFMs and will work a compressor good. that compressor you mention is gonna have a good time!

its all i can fit in my tiny one car garage for the time being. I'll upgrade later when i have more room. i just hope it works well enough to get some work done a bit faster than without it.

I repainted mine about six weeks ago in a single car garage. I did have a lot of help from an experienced bodyman. I am very satisfied with the results. Here is the complete writeup with pictures and details.

Whats the smallest sized air tank you can use constantly?

expo... I dont know if this is even possible, but thought I'd toss it out there. if air supply is a problem when painting, you might be able to just go buy a couple tanks of compressed air. I think they run like like $15 a pop. You'll have to pay a deposit, but you'll get that back when you return them. We use them a lot when paintballing. Or (I dont know if you can do this) but if you can hook your compressor up to them, you could just have some spare tanks sitting around for whenever you use air hungry tools and can't stop in the middle of the project to let your tank fill up (ie painting).

again, I dont know if this is an actual possibility, but worth a try.

 

[Hartman]

You'd use the air too fast for that to be worth while. I'd say the minimun for paint guns and DA sanders is 30 gal. Mine keeps up, but the compressor is usually always running when I use the DA.

 

[99SportX]

Do you think something like this would be able to handle painting and a DA? Is this overboard?

There is no such thing as overkill. I dunno about Coleman brand though, I would look at a different brand. I have a Craftsman and it's pretty good.

paint gun isnt the problem, the other tools are. i have an HVLP gun that uses like no air compared to a DA sander. remember, (1) a gun doesnt use much volume (2) a gun doesnt "run" constant- you're not gonna lay on the trigger and hold it for minutes at a time. your mini-compressor will proly do ok for painting but on a DA or any other air tool you will be doing ALOT of waiting. also, wait on the compressor and let it cycle... dont hammer on it and make it run forever without cutting off. compressors have duty cycles.

 

[sncwfo99]

For painting you will want a minimum of a 20 gallon tank and an HVLP spray gun. You do not want to stop and wait for the compressor to catch back up, not good for getting the paint to flow. For using air tools though you will need a bigger compressor, 60 gallon would be ideal. I wouldn't even try using a 6 gallon for painting and definately not for air tools. The motor will never be able to pump enough air to keep up and you will very quickly burn the motor up. I have overheated small compressors like that when running 2 roofing guns, which the compressor is rated for. So unless you have a use for a small compressor I would cancel the order and wait a bit longer to get a compressor that will handle what you are wanting to do.

the issue is the space that i have for the compressor in my one car garage.

attach it to the cieling or put it in your basement and run a hose.

My uncle has his compressor in the basement of his house and has a hose running to the garage. It's nice to be able to use air tools and not have to hear the compressor =P
