Reliable, simple touch-up spray gun for "in the house" touchup?

Good day gents,

What model/type of spray gun have you found to be most useful for moderate touchups (such as painting over a puttied screw hole)?

We use conversion varnish, so this would be spraying thinned, catalyzed CV.

We have tried a couple brands of air brush and have oddly found the cheap Panache brand the most user friendly, but even they are very finicky. I get frequent calls from them that the guns sputter. It's just tricky to clean them properly when you're in a million dollar house and it's raining outside.

I've found small HVLP guns easier to keep clean but I do not know if they are an actual good choice for field touchup, and I'm not keen on the prospect of a $400 gun getting stolen.

Anyone have any suggestion on what they've found most user-friendly and still give good touchup results?

Finish systems.com has a small gravity hvlp gun that is pretty dang cheap and easy to clean.. If you follow up with solvent right away there should be no reason to do a full tear down and scrub..... it could even be fitted with the small 3m pps adapter and use 4oz disposable for small jobs and make clean up even easier...
here is a link.... I have had a two of these guns for years....

That looks about right for what I'm thinking about.

Is it able to spray really fine atomization to avoid a big overspray cloud? (Low PSI, low fluid flow)?

We've used a couple of Astro's older mini guns for over 10 years. One is for stains and the other is used for various touch ups.

This is their newest mini gun. All of the Astro guns are very good to excellent. Still one of the best deals in finishing after 20 years.

Yes you can spray material super low pressure for touchups... what's more important here is how you tailor your solvent package to adhere... flow out and not be to inconspicuous on the repair... that's a trial and error thing...… That asturo looks to be pretty much the same gun out of the same Chinese factory with just a small change in appearance..... funny thing though in the asturo pic the gun is possibly defective because the air valve isn't touching the trigger...lol... dang Chinese..... maybe that one was wrenched down to tight on the adjustments for the air valve.... It's all in the details right?

Adam, thanks for that link to the Astro. About 10 years ago I worked at a shop that had a little gun that looked just like this, I had forgotten about it. Theirs was blue I think but very similar.

Shane, I know what you mean about solvent package. Anytime I'm out doing touchups I take the equivalent of a large cocktail bar with me "just in case" but always seem to do just fine by using my CV's name-brand reducer (KemVar reducer) or butyl acetate.

I have found the small Preval system the best for in home touch up. Mix 5oz. of CV, 1 Tablespoon of catalyst and 1 oz. of lacquer thinner in the glass jar, attach the aerosol cartridge and you are good to go. No on site clean up. Just take the bottle back to the shop. You can refill if more finish is needed or change out the aerosol cartridge if you need more air.

A low volume/low pressure (LVLP) gravity gun is what I think you ought to consider. It doesn't eat large volumes of air and it doesn't require a high air pressure. But don't get a cheap one or you won't have a decent quality fan. I just used a Transtar. The quality of the fan was superb.

The Astro Mini guns were always silver. Then they started color coding all of the bigger guns.

The mini holds 250 ml. The entire rig is the size of your hand. Works exactly like any other high quality gravity gun. Everything is just smaller.

I would buy a sata gravety feed gun. they also have the rps cup system so you can just leave a certain color in the cup. Their guns are top of the line and priced quite reasonable.

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).
