I once sprayed a car using a compressor (without a reservoir) and spray gun, and did a pretty good job. Of course, I lent the kit to a friend and haven't seen it for many years. Or him.

Now I find talk of 'airless' spraying. I sort of assumed that my old gun used a venturi to suck the paint out of the pot and blow it at the car, but now I'm not sure, mebbe it pumped the paint out - was that 'airless'?

Anyway, what would you suggest? I have two jobs in mind:-

Spray a chassis and axles etc etc which could be done in a day. (I've checked the over-coating times for the paints I'm thinking of).

Some time later spray bodywork, which will take two or three days.

Should I buy something to do the chassis and hire something better/different for panels? Hire looks like £120 per day and £60 day thereafter. I could buy several cheap airless guns for that.

You wouldn't have had airless, these use a high pressure pump to force paint up a very high pressure hose to a special gun, used to cover large areas quickly.
Suction fed have the paint pot under the nozzle and use a venturi to suck up paint, gravity fed have the pot above the nozzle.
High volume low pressure (HVLP) guns might be what you're thinking of?
I've never used one of them.
Things might have changed though, I've been out of the scene for years but my suction fed 20 year old devilbus on a 3hp compressor sprays chassis, axles and panals no probs, paint is paint after all, if its thin enough.

Airless spray guns are useless on bodywork you will make a bloody mess.

Promising information, thanks.

Would I be right in concluding that I should brush/roller the chassis etc, and hire a good kit for the body? Possibly easier to deal with all the sharp corners and nooks and crannies by brush anyway...

You can but I wouldn't toooo slow!
Uses more paint too.
I could spray 75-100 chassis before you brushed one!

We've just bought a small compressor, gravity gun etc etc.

Match the compressor with the needs of the gun, none of it is rocket science.

You'll need a filter can and filters as well, or you can take your chances with stuff in the paint.

Buy decent thinners, don't use gunwash stuff for thinning, use it for cleaning the gun only.

The problem seems to have sorted itself! I've been given what sounds like a fairly substantial compressor, which just needs local collection and a fettle of its pressure switch. My problem is space, but I have a plan - lend it to the workshop next door... This means that I'm probably going to buy a blast cabinet with the money I've saved on spray kit hire.

I'll certainly take your tip on both thinners ld.

Hello guys, Since I have a lot of free time with the Corona, I want to paint my speakers (4 x MTL 46 , 2 x dual 12 inch mid tops and 2 x 12 inch monitors)using a compressor. I have only roller painting experience. What type of equipment do I need(air compressor size, spray gun size etc)?I will use warnex or tuffcab. Thank you!
