Quick shine gloss coat problems.

[brannend]

I haven't been building very long so I am still in the honeymoon phase where I am trying different varnishes to find my favorite. I recently used Quick Shine floor polish (the replacement for Pledge I've read). The actual finish was good but holy mackerel, cleaning the airbrush afterwards!!! As I believed that it is a water-based product that was what I used first to clean up but it just gummed up like crazy. I tried everything else I could think of from IPA to mineral spirits and lacquer thinner. Still gunked up. I finally soaked the airbrush parts for a bit in acetone and got the gumminess to break free.

I have to think I am doing something wrong. Below is the stuff I purchased. I would really like to figure this stuff out as it did produce a great gloss and it is obscenely cheap compared to hobby specific products.

Thank you in advance for any and all help!

Never used that stuff ,
but it's an acrylic for sure via the MSDS : https://media.quickshinecleaners.co...ds-quick-shine-multi-surface-floor-finish.pdf
They are using that propylene glycol as a retarder and the butoxy as a surfactant ---> all for film forming , ,, it IS a floor coating .

I found the Pledge Floor Care to be one of the easiest mediums to airbrush - ever .
I can continuously spray the stuff , just flushing the AB with water .

Alcohols can set off polymerization of many acrylic monomers , the OH functional group acts as a nucleophile .
Don't use any alcohols , or ketones ( acetone , lacquer thinners contain this ) , while spraying that stuff .


BTW , welcome to SMA !

Oh boy… what to say? Yup… you used the wrong stuff. Not all floor care products are the same. That's why I rarely use floor products as gloss coats. Consider this a valuable lesson for you.

The only time I use floor care product is for canopy dipping (extreme rarity for me) and it clears up clear parts if I used CA glue. That is even more rare. I do like to use it to achieve glass dials on instrument panels of my aircraft kits.

I, too, use Pledge Floor Care.

I haven't used that stuff. I use Pledge revive it floor gloss.
Yes cleaning the brush can backfire. I use Windex to clean and it works pretty good for me. I break-down the brush and clean it out as best as I can. I use the brushes and push rods. For the needle I use a bit of a Scothch Brite pad just to knock anything from the needle. After I reassemble I spray a bowl of Windex through to clean any debris out.
That works for me, anyway.

Thanks for all of your input. Very helpful and much appreciated. I would try Pledge Revive it but is doesn't seem to be available anywhere.

I think I got mine from Amazon.

I believe they quit making the pledge revive it.

 

[GaryG64]

I believe they quit making the pledge revive it.

Probably because we modelers like it.

 

[GaryG64]

I found this online at Hone Depot for about $10.00.
I think it could work for you.

This is what I dip my canopies in.

Alcohols can set off polymerization of many acrylic monomers , the OH functional group acts as a nucleophile .

Can you elaborate on this in laymen's terms? I failed chemistry in HS…and actually tried.
I got the "do not use" part, but I've found that 50% isopropyl alcohol works great for an initial AB wipe down and then i flush with the stuff that is labeled "airbrush cleaner, which seems to do the same thing but doesn't smell like moonshine. My only concern was having it eat through the rubber O-rings but I'm guessing it's the residue that's not good?

Acrylic paints utilize a range of acrylic resins , some are solvent compatible and some are not .
The solvents will turn them to snot , some faster than others , and it's easy to test -- out of the airbrush -- to check compatibility .

I was saying that when spraying that floor acrylic , the Pledge Floor Care anyways , I was using only water to flush the airbrush until the final cleaning upon teardown -- then I used isopropyl alcohol and water .

Airbrush O-rings are selected to resist solvents .

What airbrush cleaner are you using ?
The Tamiya AB cleaner is the same composition as their solvent cement , 1/2 butyl acetate and 1/2 acetone , which will dissolve cured acrylics and alkyds ( enamel )

I never took chemistry in high school cuz I know I'll fail the class. LOL!

I'm glad I asked. This is all starting to make sense. Here's the stuff I've been using. It seems to work fine and hasn't caused any issues that Im noticeably aware of.


Now, I did experience the "snot" reaction you mention when trying to use Mr Color GX100 for the gloss goat after laying down the paint/camo. I mixed the gx100 with the tamiya X-20 thinner which, from what I'm gathering are not immiscible. Initially I thought it might be the high humidity we were having here in PA, but it seems that was wishful thinking. I ended up using some cheap stuff I had lying around that I'd used before without issue.

Thanks again for sharing your knowledge and not making me feel more ignorant than I already am w/ this stuff. It's nice being able to learn directly from everyone on here vs sifting through the endless amounts of questionable advice that's out there. After a while it just gets more confusing.

 

[Chuck Beemans]

What would you recommend I use to thin GX-100, GX 114 and the like?

 

[urumomo]

I don't use either of those , Tamiya or Mr Color , but that's a solvent based acrylic .
https://volksusa.store/products/497...Uny3S9N11VWcM6CbrJf8dsVSmI3m_95-qF2elApzG0uqf

You can use their thinner , https://spraygunner.com/products/gs...p6CEVo_x8y6bVk6ViJ2M2CtTGMw8fu3wDXmKsWYGzqD_V
or on the cheap , hardware store lacquer thinner .

WHICH Tamiya thinner did you use ?
There is an X-20 and an X-20A
The X-20 is enamel thinner .

It's all a learning game. A font of knowledge here so worth asking any questions. Pantherman

I've only airbrushed Future/Pledge, not Quick Shine, but I've used ammonia diluted with a little tap water to clean my airbrush with great results. I've also heard that "Simple Green" spray cleaner will also work to clean Future/Pledge/Quick Shine airbrushes.

It all depends on where the future was made. For instance. If you bought it in 2023? The alcoids in the polymer mixture sometimes solidify in the SpaceTime continuum thus making the very sought after, but highly volatile, shine.
