Dish Detergent and BBs?

I like the idea of the craft beads. I think I'll try some - they may not be heavy enough - we'll see.

 I've been using copper BBs for a couple of years now, and do run into corrosion occaissionally, but not severe.  I never have detected it in the undiluted bottles (not sure you could detect it anyway) but see it from time to time in my thinned mixes.  Just see a little rust tinge around the bbs at the bottle bottom before I shake.  Yes,I do keep pre-thinned mixes, although I've seen some say it's a bad practce.

I use Tamiya acylics and thinner.

I came across this handy dandy DIY gizmo while researching BBs in paint.  

 

 

 

I LOVE it!  It's right up my alley, got "Tim 'The Toolman' Taylor" written all over it!  Great solution!

I know, right...   At first I was like "What?"  but then I was like "Whoa!  YES!"

Know what I mean?

I use another paint stirrer like the Badger. I have one of those but I don't like it. My other one has a switch that you press down and as soon as you let off it, it stops, The badger, especially in deep bottles can be messy when it's pullled up enough to operate the slide switch. I had trouble with the motor/shaft assembly getting out of balance or something and wobbling. After it causing the 4th broken glass airbrush bottle I stopped using it.

I had my other one for years and I can't redall the brand but when/if I finally figure it out I will buy a spare.

Most times I use a Robart paint shaker because with bottles of paint that have sat for a while I can leave it in the shaker for 5 or 10 minutes.

 the dish detergant is added at mix/spraying time I beleive...

I think he adds it when he opens the jar for the first time. 1-2 drops right to the bottle, IIRC.

Those dropper tips pop off.  I have a couple empty ones that I refill with decanted paint.  That mixer might fit.

I think I tried, but I'll have to take another look.

Does anyone do this with their acrylics or is this "Old School?" Has anyone done it with Vallejo paints?

Almost - I sometimes use Liquitex Flow Aid with Tamiya acrylics, depending on the particular colour & how it's performing (or not), it reduces the surface tension & allows helps the paint behave better on occasion. Dish-washing detergent does the same thing - reduces the surface tension.

I stick with Flow Aid as who knows what is in any given brand of detergent...........................

I don't ever put anything in my paint jars. I just open them when needed and stir them with my Badger paint mixer.

I use one of these too but it won't fit through the neck of a Vallejo dropper-style bottle.

Wonder if plastic craft beads would work?  They're usually cheap for a lot of them.

Not heavy enough.

I use copper bbs in my enamels and lacquers and haven't had a problem.   Tried the steel bbs and the corrosion thing became an issue, so I tried the copper ones.  Works okay for me.

The only time I use dishwashing liquid is in my acrylic sludge washes.  I got my mixing formula from the Nov. 2001(?) issue of FSM in an article by Paul Boyer.  I think the article is available for free download from FSM.

I've used dishwashing liquid, too, for sludge washes and mixed with ground chalk pigments, to make mud on 1/72 vehicles.  In a sludge wash, it does work as a "flow agent", in that it allows you to control the flow, which is what one of the previous posters mentioned.  Without reading the context of the passage, I can't tell if you mean that Boyer means that it made flow easier.

Regarding the BB, the corrosion thing can be an issue.  My buddy Joe Leonetti gave me a great tip--he uses small pieces of glass.  I thought that's a great idea--glass is non-reactive, and if you live in a city, you can probably find good pieces in the gravel in the gutters, sufficiently ground down as to be safe to handle without cutting yourself.  If you must spend money on it, I suppose you could find small glass beads in a craft store and use those instead.  But I'm Dutchy, so if I can do it without spending money, that's gravy on the roast for me.

I don't think that BBs would work very well with acrylics as over time I think that you might get some kind of corrosion going and that might mess things up ...

I agree.  Although I have never tried it; that makes sense. 

I use bearings that come in the rattle cans; everytime I finish off one of the spray cans I cut it open and retrieve it.   I use those on my mixed paint jars with good results.  Only on enamel though.  I have seen however, glass beads heavy and small enough that can be used with acrylics.  That would solve the corrosion issue.

I usually stir my paints, more oftern than not,  I am too lazy to setup and clean the stirer.  So I shake it up instead.

 Good questions!

I remember fermis posting something about this a good minute back. I gave his stir-method a shot and I haven't gone back to shaking.

I almost strickly use vallejo acrylics and this method works well ... especially since vallejos are a little thick. Stirring helps to get everything up from the bottom that's settled. I've also hear of some taking a 10p nail and cutting/ twisting the head into a "fan" shape. I tried this but it seemed like too much work when you already have a steady supply of sprue for replacements.

This guy prefers to stir ... just make sure you have a LOW setting on your dremel before trying it....

BBs, no, never tried that. The dish soap though I have done though, but only in a sludge-wash for panel lines, recessed areas etc. In that case it allows the paint o dry slower, easier to wipe off what you don't want.

BB;s are good idea. I've done that.

I used to add a couple BBs to every bottle of paint I got, to help when shaking them up (a la rattlecan). Since I got a Dremel, and made a stir stick ("T" shaped sprue), I don't shake paint anymore. It always seemed that after a month or two, the BBs would be stuck to the bottom with hardened paint. It may be different wih acrylics, I've only ever used enamels. I have found that paint seems to last a lot longer when it's stirred up with the Dremel.
