Electric spray gun
Anyone ever sprayed a car with an electric spray gun ??. My dad used to do it years ago but I was too young to remember what sort of finish he got, or
how much final surface finishing he had to do.

it was a long while ago, but i did have a go with one, "wagner" i think it was called, now i don't profess to be an expert paint
sprayer but the results i got from it where "shocking" may have been me, maybe the gun, maybe both but i personally would'nt try
again.........

I once did a car - 25 years ago - with a burgess electric gun.
bloody awful.
unless you want a nice orange peel finish. I think these things are good for creosote or the like.
I have made a really good job of a car about 8 years back, using a std bottom fed air operated gun.
dont use a lekky gun - itll give a crap job.
unless Mark can say otherwise

I had a Burgess gun ages ago and have to agree with Steve, the finish left a lot to be desired.
Bite the bullet and get a compressor, after the initial wallet shock you'll wonder how you ever did without one!!

If you are painting the fence then OK, but other than that don't bother.
Many years ago you could get synthetic paints that would work great with a leccy gun. However these days you are very limited in materials you can use
and they don't spray too well with an electric gun because they get heated by the gun and come out as spider webs!
Many years ago there was a synthetic material called QuickLine made by PPG (where I worked) which could be sprayed or brushed and flowed out to give a
beautiful gloss. It made cellolose look matt by comparison. This could be sprayed by an electric gun. However it was phased out due to changing
regulations.

Get to the Aldi supermarket.
They are doing a 1.5hp oilless compressor and some cheap attachments this week. Powercraft £69.99 looks like a SIP, attachments £19.99. I use a
gravity feed gun like the one in their kit and it works well with cellulose or synthetic. Get one quick if you want one 'cos last time they all
ended up on ebay days after the offer ended at £99.99 buy it now (profiteering)

thanks
compressor it is then, however just one final question. I know a chap with a small compressor but he complains that it only holds enough air to spray
for about a minute before it has to recharge. He moans that this has caused he problems when spraying cars ??

That is down to free air rate as well as the volume it holds. Mine is 30 litres, but i've never sprayed with it so i have no idea if that is
good. Rather noisy though.
Get the biggest you can, mine at machine mart was 110 spondulies, a friend has a similar one he uses for spraying small jobs.
maybe ask at the shop, and they'll undoubtedly sell you the biggest and most expensive one!

I sprayed my old mans Morris Minor years ago with my cheap Clarke (Machine Mart) compressor and gun. To get a decent finish in cellulose, when the gun
was half-empty (natural pessimist) I topped it up with thinners and carried on spraying until spraying virtually neat thinners for that mirror finish
(with flies). The weather was hot and some of the paint would start to set while I was waiting for the compressor to re-charge. I couldn't get
the required smoothness on the panels because of this. Although I have to say the o/s front wing was a work of art. Still makes me happy when I see it
today.
A friend and I tried to respray a Land Rover with an electric gun. It was utter shite. We bought Tekaloid and brush painted it instead. (nice )
The moral of the story, get lots of CFM and a big tank.
Neil.

Mark might be the best one to give advice on this.
I have read somewhere that you need at least 7 CFM to power a spray gun. Most of the ones in machine mart are around this level - you seem to have to
part with a lot of spondoolies to get much higher.

Spraying only?
If you are looking at a spray outfit try the HVLP setup.
http://www.frost.co.uk/item_Detail.asp?productID=8772
I used one of these years ago and found it easier to get on with than a compressor fed setup. It works on a turbine system. If you want to use a
compressor for other than spraying you should be looking at about 12cfm+ to run tools like die grinders etc. Your free air delivery is usually around
2/3 of the cfm figure and this is the part that counts. Put the price of a decent spraygun into your budget and you will be looking at a tidy sum.
Having said that my compressor cost me £350 and my gun was £57 and I now use a £20 gravity gun with a 1.4mm nozzle for most locost size jobs, but they
were bought when I used them for a lot of other stuff.

Hvlp / small compressors
I would recommend HVLP for spraying in lieu of the small gravity gun with HP air, with a small amount of practise, the finish with HVLP is much
better. If you chose to buy a small compressor aim for the 7-10cfm range, I use a cheap SIP on wheels for mobile work that chucks out 10cfm, that also
runs my air die grinder and sander all day if required. Well maintained air tools outlive electric ones, in an enviroment with lots of dust and
hazchems paints, solvents, resins etc etc much safer too.

Was readin an article bout spray guns and the like and the apollo Spraymate 400 got a really good review - 150 quid though so it's not that
cheap. Its a hvlp turbine system jobby.
Hope this mite help
