why don't I buy a good one then. I keep saying this is the last spray but a few months down the track out comes the gun and it starts all over again. ive even been paid to spray a few cars for people and knocked back an old falcon re-spray about 3 months back. reason being they start off happy but in the end think they are getting a $10k re-spray for a fraction of that BUT think they are spending the big money! so I just do my own and let then get .....baked
so a supercheap 40 litre compressor will do the job plus that $55 spray gun will give you great results and spray as good as you can handle it. you'll require a pretty good face mask that's important rather than breath in fumes which become overpowering with acrylic and enamel paint and 2pac -forget it!
so you have the info on the compressor/mask/gun/ and now the water trap. I tried many which hang off the compressor plus ran them in line with a trap right before the gun but in most cases right in the centre of a big panel - mainly a bonnet out would spit the water droplets from the gun -job buggered. this went on and off for quite some time till i'd had enough and finally mentioned it to the auto paint supplier
he told me -you need a toilet roll filter trap -and that is exactly what it is. you just unscrew it and add a full roll of toilet paper and screw it back up and connect your in/out hoses. using this method of a water trap I have been able to do whole car re-sprays with no water spits on your freshly painted surface. plus it does work great. you can unscrew the lid and pull out the roll and feel the dampness from the water it has extracted from the line.
then you just toss away the old toilet roll or let it dry out and replace with a new roll. you can even take it back inside and use it yourself
these filter holders don't come cheap but you will only ever buy one -once. I think I paid about $150 for it many years back -could be 10 plus years but with the internet about these days -you could probably chase them down.prior to a painting session like yesterday's front bar and especially if I have not used the equipment for a while -here's what I do
1. turn on the compressor and let it go half cycle and turn it off. slowly undo the plug at the bottom of the compressor and remove it totally. be careful it doesn't blow out of your hand. this will get rid of any water trapped in the compress from the volume of air exiting the chamber
2. plug back in the compressor and connect your hoses and the trap. turn power back on and take to half pressure. connect the gun and squeeze the trigger and empty the whole contents of air from the compressor through the spray gun.
3. pull the disconnect plug from the gun and tap the compressor lead on the cement floor to see if any water is present in the air lines. following what I said and using the toilet roll filter -all will or should be good. I had not used my compressor for months and although water came out of the compressor outlet yesterday - nothing from the line or on the work.
well that's how I do it. if it helps...it helps if not you got something to read and fill in time
