Hi!

I have a Lexan body coming from FeeBay . Someone tried to "paint" it !

Anyhow, I heard somewhere maybe here that you an use warm vinegar to remove paint ??

I know that you can use it for removing decals, because I've done it !

Or maybe there is another method ! Thoughts ?

THANKS !! Ted

I should have snooped around first ! I guess you can use brake cleaner , good old acetone and even this stuff called de-sol-it graffiti !

Anybody have experience with these ?

No help but I would think it would depend on the type of paint used.

I've heard that DOT type3 brake fluid applied with a cotton ball can soften the paint without harming the lexan.

Whatever you try, I would experiment first on a body you don't have an emotional attachment to.

Brake fluid and denatured alcohol both work on different paints without damaging styrene and most resin bodies.  I recall they cloud lexan windows and deform butyrate vintage shells

Super Cleaner, think I got it from Pep Boys. Straight, not diluted, 24 hours. Think this is a Lotus 40, don't recognize maker, odd engine detail, came is same batch as Thingie "Rocketeer".

Super Clean, Liquid Drano and other caustic solutions containing sodium hydroxide or sodium hypochlorite are capable of safely stripping paint off of vintage butyrate or styrene slot car bodies, although they don't always work on every color or type of paint. The one time I tried it on a lexan body however, the body became very thin, and cracked along the edges and molded creases.

Superclean is the best I have found, but it will take off your skin!   Wear plastic gloves when you use it, or rinse it off as soon as you get it on your fingers.

I use an oven cleaner with caustic acid (not the eco-friendly kind!), and it works very well on old butyrate bodies. Doesn't hurt the plastic at all. 

 

Also, is the body you're getting really Lexan, or just an old vac-form body (mostly butyrate)? Not sure about what products to use on actual Lexan, because I think the paint "bites" more into that plastic. If it's a 60s body, the chances are it's butyrate and not Lexan... but from about 69 on (to be confirmed!), bodies are mostly Lexan.

Mark, just incidentally, the body is a Lancer Lotus 30, also found in the Classic Manta Ray packaging as a spare body:

And yes, Castrol "Super Clean" is I have also found, the best way to deal with unwanted paint on a butyrate or polycarbonate body.

Yes, and a pointier nose. When I bought my Manta Ray I used the Lotus body on an AMT chassis, and still

have it. It still runs and has been to Chicagoland many times. The Manta Ray still had it's original body until

we ran a Manta Ray class at Mike's, pushed by Ray Price. Unfortunately, the body got busted up and had to

be replaced by a re-pop.

Mark,
there were at least 12 individual molds of the Lancer Lotus 30 as many tools were needed to face the required production. Think that over one MILLION of these bodies were produced, and we have several variation of that very body at the LASCM. That "4-carb" version is just one tool, but it is definitely the same basic pattern.
We see variations in lots of bodies, especially the Pactra models, but also many Lancer. Detailing being done by hand, it explains a lot on the little differences... :)

Hi ALL!
Well this stuff WORKS !

Below are before and after pix of the Cheetah !

It took about 4 hours to get rid of the silver and another hour to get rid of the red hood !

After rinsing and drying I get a red ting , but otherwise it's very clean !

Super Clean !

I bought it at my local Aubuchon, for $12.99 for the gallon ! .

THANKS, Ted
