Dandy Dan Posted March 26, 2016 Share Posted March 26, 2016 I picked up an original 1968 promo car that is wounded. I want to fix it with some good old styrene. What kinda adhesive will bond well to both materials? I've tried some 2-part 24hr epoxy before - didn't work very well. Someone with first-hand experience, please. Thank You Quote Link to comment Share on other sites More sharing options...
espo Posted March 28, 2016 Share Posted March 28, 2016 I have used Zap-A-Gap Medium CA+ and have had positive experience bonding plastic and resin both. Quote Link to comment Share on other sites More sharing options...
jeffs396 Posted March 28, 2016 Share Posted March 28, 2016 Any good liquid styrene cement (like Tamiya) will work nicely on the old MPC promo... Quote Link to comment Share on other sites More sharing options...
Jantrix Posted March 28, 2016 Share Posted March 28, 2016 So the promo isn't made from styrene? What's it made from? Quote Link to comment Share on other sites More sharing options...
Art Anderson Posted March 28, 2016 Share Posted March 28, 2016 So the promo isn't made from styrene? What's it made from?MPC promo's were all made in ABS plastic (as were AMT promo's from about 1962-onward, JoHan from (I believe) 1963. While ABS can be glued to ABS with liquid cements (they did that at the factory in promo-production frequently!), ABS doesn't bond well with polystyrene this way. CA glue would be a very good, and fairly reliable alternative.Art Quote Link to comment Share on other sites More sharing options...

Gonna splice in one from a '69 kit body with a bad roof. Will keep this in mind and run some tests before I commit with rare parts. Thanks, Art!

peteski Posted March 30, 2016 Share Posted March 30, 2016 ABS (Acrylonitrile butadiene styrene) is a type of styrene-based plastic fairly similar to Polystyrene (which modelers coloquialy call "Styrene"). ABS is also sometimes used for more recent plastic model kits. Both types of plastic can be welded using solvent cements used by modelers (even though the instructions on the bottle do not specifically say that). If you want a specific solvent which mentions that it can bond both ABS and Polystyrene then use Plastic Weld from Plastruct.Of course CA glue will also work well on both of those types of styrene.
