Scooterotica

Evening all,
I have been a given an air compressor and fancy having a go at spraying some old panels that I have in the shed. I've never used one before and need some advice on which spray gun attachment I need to buy. Had a look on E-Bay and there are loads on there. Any thoughts much appreciated

Many thanks!

Scott

I've had good results using one of these.

Thanks, and what paint would you recommend - I see there is 2 - cellulose and 2pack

I used one of those to spray my cutdown after starting off with a full size gun, got better results from that using cellulose once i got it set up, only problem was i was forever filling it up as the paint pot doesnt hold a lot

have a look on your compressor and see how many cfm(cubic feet per min) it can pump, this dictates how big a spray gun you can use. eg the size of the cap on the front of the gun.the temperature can realy effect paint spraying, if you dont have a heated area to paint in it will bloom after you have sprayed the paint, it goes like a milky colour and a mat finish,also you need good ventilation and good mask or respirator, celly paint is simple to use but 2 pack is very toxic or fatal i would use celly to develop your skills first, ive painted a few scooters and its nice to look at a good result when you have done it yourself. i am not an expert and im sure more advice will be offered, good prep work is very important, bare clean metal, degreased then etch primed is where to start.

yes that's right.

eg the size of the cap on the front of the gun.

yes ok.

the temperature can realy effect paint spraying,

well yes but if using two pack it's important to maintain a steady temperature to help the drying more than anything.

if you dont have a heated area to paint in it will bloom after you have sprayed the paint,

nonesence, blooming will only occur when the temperature drops below the dew point

it goes like a milky colour and a mat finish,

yes if you allow it to cure in a damp atmosphere (nothing to do with temperatures)

also you need good ventilation and good mask or respirator,

celly paint is simple to use

sorry I've no experience with celly paint so wouldn't be able to comment

but 2 pack is very toxic or fatal

well I'm still here after spraying several hundred thousands of litres of the stuff so can't agree in full but if you are using the iso-sianide stuff (found in the polyurethane variant) you'd better watch out !

i am not an expert

no me neither.

degreased then etch primed is where to start.[/quote] shakes head and leaves in disgust!

That gun has a huge 2.0mm set up and has a high cfm (uses a lot of air)
I have had good results with these http://www.ebay.co.uk/itm/HIGH-QUALITY- ... SwHMJYD7mM (I use a 1.8 for primer and a 1.3/1.4 for base and clear) using a 14cfm compressor with a 300L tank
I sprayed my mates side panels using his compressor which is a lot smaller than mine (about 90/100Ltr tank) and it didn't struggle to keep up
Also if your new to spraying and depending on the size of your compressor you would probably be better with an LVLP gun as in theory you can spray less material, have less paint blowing all over the place, have more control and go slower with less build up

They normally come with two nozzle sizes. You can choose which sizes you want before ordering. With the paint I used from Lambretta Paints it only needed 2.5 bar of pressure to get a good finish. You can get good results with most compressors. It's all about the prep really.

Also remember all air compressors produce water so make sure you have a decent in line filter/water trap otherwise you will end up with globules of water on the finished job.
The last time I used an air powered spray gun was before all this LVLP and HVLP stuff came out, Sagola and Devilbis were the guns of choice back then with a few Chinese knock offs being available, well although they looked the same the results were very different so buy something decent from a specialist supplier.

I'm not an expert either but have sprayed several cars and scooters over the years and would agree with pretty much all of what holty has said, especially the comments about 'bloom' also called 'blushing'. maybe it is technically the 'dew point' but I've had it several times and would say that cold temperatures and 'dew points must be related as it's always been cold or damp conditions where I've had it. Warm air whilst spraying and warm air for a couple of hours after until it's fully air dried.

Celly is very forgiving in that mistakes or repairs can easily be corrected with an invisible result as the new paint will melt the old with a seamless finish. 2k is 2k, all contain isocyanides which are toxic and professionals use air fed masks which also protect their eyes. This is because the effects are cumulative and builds up over many years. But so long as you aren't doing it day in and day out you can use a 2k filter mask as sold by 3m with good ventilation (you might want to consider family, pets, neighbours whilst spraying too
