Hi folks. I'm thinking about buying a small spray gun to prime and paint little areas like under the bonnet and wings.
I dont have extraction and don't want to gas the neighbours so I thought a lvlp gun would be good. Trouble is I can't find a small one, say, 0.8 or 1 mm with a 125ml or 250ml cup. They seem to start at 1.3 with a fan size of about 10", way too big for my tasks.
Does anybody know of a reasonably priced one or can anyone tell me why they don't seem to make them.
Otherwise it's going to have to be a Sealey hvlp 0.8 setup which will create more airborne dust and fumes but not as much as a conventional gun.
Thanks
Alan.

Carefully adjusted the sealey one will give minimal overspray and unless you are on the expert side of average will give acceptable results.I have a Fastmover mini gun which is almost identical and it is more than OK for£15,read all about protecting yourself and others then buy a brush.Enjoy,Steve..

Thanks Steve. Yes the alternative I've thought about is a roller for large areas and a brush to get into the corners. Anybody got any recommendations for rollers that'll stand up to automotive paints?

I would look for a gun using the term "touch-up" or "mini" gun. As long as it doesn't exceed the airflow rating of your air source.

 

Sure, people have had some success with rollers, but unless you don't care about the final finish, I think it greatly increases the labor to get a good appearance. I guess if you're satisfied with a "3 meter" paint job, then it may be a viable option.

I prefer RP-guns (reduced pressure) to LVLP (low volume low pressure) or HVLP (high volume low pressure). RP-guns need wayout less air capacity of the compressor. But I use LVLP for primer and filler with a 1.8 nozzle.

Thanks chaps. I'm thinking I can have a practice under the bonnet and wings where finish isn't so important, see how it goes and make a more informed decision on what to do with the outer panel paint. I'm using Eastwood rust encapsulator platinum as a primer coat for under bonnet and wings.If I do the top coating I know it'll have to be celly.

If you are going to try a roller to apply the cellulose paint, you need to make dead sure that the paint is suitable for roller application.

 

I have never heard of an automotive cellulose\lacquer paint that could be applied using a physical contact tool. This type paint is very thin. I have only heard of thick enamels being used for roller painting.

 

Even spraying a cellulose paint usually requires multiple coats (more than 2), and if one really wanted to try and use a roller, it has to be thick enough to go back later and flat out all the roller marks. The equivalent I'd guess would be over 20 coats sprayed.
