I bought an old Magnuson Models kit of merchants row. it is covered in sticky resin. Does anyone how to get the sticky stuff off?
Thanks
Well I doubt the resin used to make it is degrading. Since thye are made from organic chemistry materials you are going t need one of the more harmful (carcinogenic) organic cleaners like acetone, cholrethane or benzene in all likelyhood. I would try a strong grease cutter first. Then I would go to oven cleaner as caustic soda might work and then on to the big boys with rubber gloves and breathing upstream outdoors of the fumes. Try everything on the back of the parts first with just a small amount to see if it attacks the material and be ready to pour a gallon or so of water on it if it does to stop the reaction.
A second thougt. If the household cleaners won’t do it try mineral spirits, turpentine or paint thinner before going to the haz mat materials.
I had one of those and built it. I couldn’t get thye stickeyness off either, so I just sprayed it with a flat gray plastic paint to primer it (spray can). All was well after that. I think the problem was the resin that was used (Polyester). It isn’t like the resins of today.
I built the kit first, then primered it, then added the detail castings and other parts. The details were hand painted after the final color coat. For glue I used ACC.
You can’t get it off because the parts aren’t covered in sticky resin, the castings are sticky resin!! All those Magnuson kits were that way. Walthers (who bought Magnuson) eventually reissued some of the kits in styrene plastic.
As noted in some earlier posts, cleaning the parts with soapy water and then painting will seal the parts in (or you can build the model then paint it.)
T’ve spray painted the sticky walls before with Floquil or Testor’s. You can prime them first before working on the kit. “Mold release” or resin or whatever it is, the worst thing I’ve had problems painting over is my own fingerprints!!! Be careful filing or trimming the walls, they’re kinda brittle.
Magnusen models were made of Polyester resin which is sticky to the touch. You can spray with auto primer. Use CA to assemble.
