Devilbiss SLG-610 or FLG-5

[Tan91]

Right. Need to buy a spray gun as I can not afford painters to paint, and have had some practice a while back and pretty confident in spraying my wings/doors/bumper/front valance/boot/SE spoiler.

Been looking into these guns. They are "gravity fed".

Devilbiss SLG-610 (StartingLine) @ £60-ish


Devilbiss FLG-5 (FinishingLine) @ £100-ish


SLG-610:
Gravity Fed / 4.8cfm / 550ml cup / Requires 5cfm compressor / Recommended to work @ 2.5bar / maximum is 4bar

FLG-5:
Gravity Fed / 9.8cfm / 560ml / Requires 10cfm compressor? / Recommended to work @ 2bar / maximum is 4bar?

What would you choose as these are the guns I am looking to get within 2 weeks time. Need to know what compressor would be recommended as I am using 2K paint from a reputable local paint shop.

I am good with the body work i.e straightness and smoothness of panels and also primer. Just need help with paint guns to go for and compressors to run them.

Help is much appreciated sorry for the longness but just making it clear on what I'm on about! Cheers Guys

Be aware that as far as compressors go, you're not really going to get more than 11cfm out of anything that runs on standard electricity. If you go three-phase or even petrol then you can have bigger motors, but don't believe the hype of any compressor offering a 3hp motor and 14cfm - it just doesn't happen.

With that in mind, I'd suggest the SLG purely for its lower air requirements. What you haven't mentioned is what size tip either gun has; if you're shooting primer as well as topcoat, it's hard to find one gun that can do it all since primers often require a bigger tip (1.4+) to thinner topcoats.

If this is your first gun, have you looked at the Sealey Gold range? They were highly recommended for beginners.

Rememer you also need filters (20 and 0.1 microns) just after the compressor, as well as water traps on the hoses and a decent air mask (mig-welding.co.uk recommend air fed as a minimum). With that in mind, don't go splashing all your pennies on a top-of-the-line DevilBiss gun when it's only 20% of the equipment you need.

Understood. I was watching a few YouTube Clips, and they say that a 1.3/1.4 tip is sufficient for a top coat. What do you think?

And with regards to the "Sealey Gold Range", this one? :-


Sealey Gold Series Spray Gun @ £35.95 + P&P
Gravity Fed / 6-11cfm / 600ml / Requires 11cfm compressor / Recommended to work @ 2bar / Max 3.5bar.

Comes with a 1.4 Tip, Suitable for top coats? My E30 is Brilliantrot so its a straight colour no lacquer involved. however this gun is available in 1.7 & 2.0 tips.

I have also done extensive research as to how to keep guns clean through out the process, and ventilation for the 2K paint I have designed so that I get fresh air from out side only.

And as far as compressors go I can just hire one out from HSS, as my Uncle works there so Hiring out a powerful one should sort out the air feed right?

[Grrrmachine]

You'll need to find out what compressors your uncle has for hire, but the power, and therefore the max cfm, is capped by the electricity you can feed it with. That's why I mention 11cfm as an absolute maximum to expect from any compressor.

And if you rent it, you need to make sure it comes with PROPER filters; spend all your time on prep and then get fish-eyes and silicone contamination from lack of filtration, meaning hundreds of pounds of paint instantly ruined means

I've done all my painting with one gun; it has a 1.4 nozzle and while I had to thin the primer a bit, the topcoat and clearcoat went on wonderfully. The bigger nozzles are for thicker media, so high and ultra-high build primers.

As for the gun, the Devilbiss SLG-610 is apparently a chinese-made of piece of sh!t, and not recommended. The Sealey one is S701G

Hello, the compressor we have is a 3bhp and 14.7cfm. It's V-Twin and uses 3Kw of electricity.
Are these figures optimistic?

[Tan91]

Ok yeh I'm with you on the nozzle size, so 1.4/1.3 is fine then I guess.

With the compressors I can get a discount, and I would make sure it has plenty of cfm to start with.

If I was to get one, I was thinking of this compressor; AirMaster Tiger 9/30:-

Spec:-
8cfm Displacement
2hp 230v motor
24 Litre Air receiver (CE Certified)
10 bar maximum working pressure (145psi)
Includes wheels & handle, pressure regulator, twin gauges & safety valve
Weight 27kg

Would this be suitable to run the Sealey S701G?

[redcar]

We have an AirMaster one, it's the V twin 14.7cfm 100 litre 3bhp one.
It's very good quality and does the job. Brother sprayed his engine bay with a few coats and no problems with the compressor.

The specifications suggest the gun requires 6cfm-11cfm. If you're doing smaller areas, that compressor should be fine. The compressor may struggle doing a whole car, but i've no idea tbh.

It may be worthwhile getting at least a 50litre air master one. The tank will empty very quickly with 25l.

If you skipped the long-ass description I gave in the beginning or fell asleep lol, I will be tackling:
Both Wings
Front/Rear Bumper
Front Valance
Both coupe doors
Bonnet
Boot
SE side skirts

But not all at once, My garage only has space for both wings and a bumper or valance, will be doing it slowly 2 maybe 3 panels at a time maximum. Obviously what ever fits i.e bonnet would be done by itself. This is including enough space to move around comfortably to apply paint correctly at the angles required.

I think you may need at least a 50L tank then.

Sounds like you're doing it exactly like I did mine; I did all my panels separately too.

Redcar, 14.7 is very optimistic. 14 in the book usually translates as 11 out of the nozzle. But the 11cfm for a gun is if you have the fluid tip all the way back, full throttle. So do your paint in sweeps and you won't have any issues.

With either a 24 or 50L tank, you're still going to have the pump running most of the time. That's not a problem, it just makes the work environment noisy.

Indeed that's correct. However a larger tank, especially if you are doing the panels seperately will mean less chance running out of boost mid panel. 25L does seem very small for spraying panels.

[Tan91]

Ahh ok, well it will only be done for a week I guess and during the day of course and neighbours where pretty cool when I first had my sound install done which was "A LOT OF BASS".

So all in all the Airmaster 9/30 should be sufficient for the Sealey Gun? This is going with the fact I will be doing a few at a time...
