Might even splashout and grab a binks or devilbiss one day.

Hi ya Harry,

I've used the S770 for years & it was fine for me.

Ask Shane about IWATA guns, they have a VERY GOOD reputation, if you want to go up-market.

"Hmmm I have two different model IWATA guns that have the air adjustment knob at the base of the handle.....Or am I only dreaming...will have to check on that tommorrow"
Most have an air adjustment on the lower part of the handle, even my samson has.

Sorry Soren,

Where did 'purchased 9 days ago' come from? :confused:

Thanks Shane!

Now kiddies these are BMW class spray nugs!
What we are talking about (S770) is a good Commodore quality nug!

So there should be no problems

This is where the comment comes in, ie only purchased 9 days ago from B.....gs :confused:
I hope the gun will be OK for finish applications, with the 'less than perfect' compressor

Hi Soren,
I believe your issue is not the compressor nor the spray gun as being any problem. The pressure you mention is way to high firstly for most guns. The viscosity of the material your trying to spray is way too thick and therefore your trying to move thick material into a air borne mist that is spray painting.

You need to determine the composition of what your spraying in particular the solvent that dillutes the spray medium. For example if your usig auto acryl lac then thinners for that particular paint is required. If your using house paint that is water based then use water to thin the paint etc. Oil paint would have to be thinned using turps etc.

Your trying to transfer material that is wrongly thinned for spraying and this is the "poor" transfer and spattering of paint. This is where your going to burn your compressor out for it has to work like a "dog" moving liquid lead from the pot.

Always check if a particular paint in fact is recommended for spray applications.

Have fun! You have a reasonable set up but a very thick medium laboring your compressor.

Nah Id say more like a Hyundai excel, the samson is more like the commy/falc range.
They all still get you from A to B!

I was hoping that was the case, and I now have a 'viscosity' cup which "should" enable me in thinning the paint appropriately.
My main question is still outstanding however, in that: "is an HVLP gravity gun better for the compressor I have (8cfm GMC) ?"

I really appreciate all the responses received so far

**Harry72** · 29th March 2005, 10:14 PM

Dont bother with them unless you just intend to paint stuff where a nice finish isnt needed.
Still it wont hurt to have both types...

Is this the fastest growing thread or what!!!

**Harry72** · 29th March 2005, 10:15 PM

viscosity' cup, I use a stick!

ROFLMAO

How do you time your stick ?

**violincrafter** · 29th March 2005, 10:33 PM

The diff between the guns are in the hands of the operator and like all things its a matter of personal preference. I like suction feed guns and also gravity HVLP types. Each has its benefits and probs. They arnt that pricey either depending on brand names. The suction types leave a little paint in the pot and this is to leave any particles there. But then again if paint is filtered there should be no particles there in the first place but then again<<<what if? A gravity gun will clog right away if there is poor shop practice or other reasons. Gravity also poses a problem with poor seals after time. As with all things liquid via gravity likes to find its way into many places it can escape. To answer your question try both and see which you like the best without any spills.

Your compressor should handle both and of course the gravity feed HVLP will be easier on the unit but technique will play an important role as will the seals be and hopefully no paint consolidation settles at the bottom or should I say at the top to require a clean of this type of gun and cause dreadfull splattering and clogging early in the work

. Gravity wants things to settle and find points of exit.

A gravity gun seems like a waste of money for fence painting as is a good arnold suction gun! :eek:
