Hi all, i want to give my dutton a re-spray and need to know what the best way of doing it is, is the low pressure high volume sprayers you can get in macro anygood???? or is it best to get a compressor and paint gun like the norm. anybody help????? cheers

Billy, HVLP guns need at least 17cfm to work properly, when they say High Volume, they mean it.

You should be able to get a devilbis JGA or the gravity version of the same gun (even better) off ebay very cheaply these days as no bodyshops use them anymore, and millions were made. They are about the best guns ever made for standard air consumption guns.

so mark, do you recomend getting a hvlp gun then?? or do they give bad results...... i dont have a compressor cheers

We use HVLP's at work, I think you must be talking about something else as they are compressor driven. You can use a HVLP gun, but you need a seriously big compressor to run it, a piston one will be on the limits, a rotary screw one will be fine (but cost thousands)

Mark, i mean the electric ones, like made by powerdevil, etc. cheap and cheerfull

You can pick up small compressors for cheap these days. They normally come with a few accesories, one being a gravity fed spray gun. I think Lidl or Netto had them for £60 the other week. Will probably be enough for spraying, but not sure how great the guns are.

Nissan use devilbiss robots on the paint part of the production line up at the plant in sunderland. If i cant get decent results with the spray gun ive got i may look at getting a devilbiss one off ebay.

The ones like a turbine with their own dedicated gun are not bad tools, a bit like running them off a vacuum cleaner in reverse. I used to borrow one years ago for bits and bobs. I painted a whole car with it once and it came out quite well. Also used a Wagner electric gun but not to any great extent, they are alright for spraying creosote on fences.I got a decent low pressure gravity feed gun for £23 and it gets used for everything these days. edit:- buying an expensive gun won't make you a better painter.

It odes not matter so much wghat you use to spray a car with if your preperation is not done properly any imperfection on a car may not even be noticed when its finish is old and tatty but as soon as you go to put on some paint it stands out like a dogs danglies . Thre will be some books on painting cars in your library or tecnical book shop do some research first because it is very easy to spend a lot of cash on gear and still end up with a less than wonderfull finish . I have painted a few cars over the years with some crappy gear and it can turn out OK but a lot of the skill is in understanding how the paint goes on from the gun so what ever you get practice on some other things before you try the car . Keep the gun moving and try to keep your distance from the job consistant and don't try to put your pint on to thickly or you may end up with runs .
and that will give YOU the Runs

Oh one more thing if you can only afford a small compressor you can make it work better by increasing the storage . I have used a large out of date empty gas bottle and after removing the stop cock found that common plumbing adaptors enabled it to be hooked into the compressor .system.

Ideal for staining wood or for insecticide, not for the car

Prepaint spirit wipe, its made for the job, available at all good bodyshop suppliers. Don't forget your tack rags!!

I used one years ago to repaint the fron end of an Alfasud after replacing panels due to the tin worm they suffered (it was only about 5 years old!) and achieved a reasonable result. It required quite a bit of rubbing down afterwards, to the extent that I practically had no fingerprints left, but looked good.
