Olderisbetter Posted October 16, 2018 Share Posted October 16, 2018 I have acquired 56/57 Lincoln Continental Mark II promo car. It needs paint stripper. I usually use brake fluid. Is that safe to use in that era promo car? If not, what should I use? Thanks. Quote Link to comment Share on other sites More sharing options...
Tom Geiger Posted October 16, 2018 Share Posted October 16, 2018 Nooooooo! I've seen those old promos blow up like a Gummy Bear in Vodka from brake fluid. I don't know what modern alternative would be safe with that plastic. Quote Link to comment Share on other sites More sharing options...
Olderisbetter Posted October 19, 2018 Author Share Posted October 19, 2018 Tom, Hahaha....Thanks. At least now I know NOT to use it. Quote Link to comment Share on other sites More sharing options...

MrObsessive Posted October 19, 2018 Share Posted October 19, 2018 Chuckling here at work over Tom's comment, I forgot to mention an alternative. Perhaps you can use Easy Oven Cleaner (yellow can)? Maybe using a Q-Tip swab or something, you can try to apply it in an unseen area on the promo and see if it affects it or not. Other than that, I'm not sure what else may work on it without causing some drama. Quote Link to comment Share on other sites More sharing options...
Oldcarfan27 Posted October 19, 2018 Share Posted October 19, 2018 (edited) I'd be interested in knowing what does work on removing paint from acetate plastic as I have a few brush painted acetate cars that I want to restore, but can't until I find a safe paint remover first. I posted a thread trying to gather junk acetate from fellow builders to use as samples to try to find a paint removal solution, but I got no response.

disabled modeler Posted October 20, 2018 Share Posted October 20, 2018 I have had oven cleaner do the same thing to early promos once on a 60 Ford Galaxie HT....it ruined the thing. Quote Link to comment Share on other sites More sharing options...
Snake45 Posted October 20, 2018 Share Posted October 20, 2018 Somewhere I've got a badly warped early Corvair 4-door promo. If I can find it, I'll see what rubbing alcohol does to some small hidden area. It sounds like oven cleaner (lye, basically) is a no-go.

Deuces Posted October 20, 2018 Share Posted October 20, 2018 How about the old "stand by"????.... Castrol Super Clean.... Quote Link to comment Share on other sites More sharing options...
Olderisbetter Posted October 21, 2018 Author Share Posted October 21, 2018 I guess we still don't know. Castrol Super Clean is not available where I live (Thailand). I can get sodium hydroxide (lye), but now am afraid to use that. They are made from acetate plastic? I'll have to try to research that. Thanks for all the replies and open to more.

Thanks for all the replies and open to more. Sodium Hydroxide (Lye) is water-born, and in my experience, does not at all affect plastic, even the very old Tenite (Acetate) plastic. FWIW, Tenite ceased to be used for making promotional models by about 1960 or so, when more modern plastics became available. Art Quote Link to comment Share on other sites More sharing options...
Oldcarfan27 Posted October 24, 2018 Share Posted October 24, 2018 Anybody have any experience using paint thinner, lacquer thinner, vinegar or even moonshine? I'm curious to know what is safe and what is not. Quote Link to comment Share on other sites More sharing options...

I'm curious to know what is safe and what is not. Lacquer thinner or acetone would almost certainly melt the plastic. Some "paint thinners" (that covers a lot of territory) might as well.

There are many different varieties, with differing properties...even many different specific formulations under the trade-name "Tenite". 12 hours ago, Art Anderson said: Sodium Hydroxide (Lye) is water-born, and in my experience, does not at all affect plastic, even the very old Tenite (Acetate) plastic. FWIW, Tenite ceased to be used for making promotional models by about 1960 or so, when more modern plastics became available. acetate is soluble in many common solvents (especially ACETONE and other organic solvents) and can be modified to be soluble in alternative solvents, including WATER. acetate will absorb moisture if it's soaked. It may warp badly when it dries out. acetate is easily weakened by strong ALKALINE solutions and strong oxidizing agents.

Maybe try some rottenstone or pumice with a damp toothbrush to prevent damaging fine details. I’ve seen it come in 600 grit. These inert powdered abrasives might remove paint without melting the “plastic” and should rinse away with nothing more caustic than water. Just a thought!?

Oldcarfan27 Posted November 3, 2018 Share Posted November 3, 2018 (edited) Just a thought, if acetate is wood based, do you think a paint stripper that is safe for removing paint from wood surfaces is gentle enough for it? What about Murphy's oil soap, or other wood cleaners? How about Pine Sol or simple ammonia based cleaners like glass cleaner?

BMXNBULLDOG Posted November 8, 2018 Share Posted November 8, 2018 Ok, not to take over the post, But, What do we use to strip old white paint off of tires? Does the Super Clean hurt tires? I don't want to come back to 2 black lumps in the bottom of my pond. Anyone have experience stripping paint from tires? Quote Link to comment Share on other sites More sharing options...
