Hi Ya’ll!

I got to thinking about something concerning Plastic for scratch building. I know many have talked about the plastic from Auto Dealership tags and Real Estate signs. Be careful here! I have run across some that even the plastic glues made for certain plastics won’t work on. I tried an experiment. With the promo tag from where I bought my 2016 Chevy Trax-LT I took that tag and attempted to use it for some sheet work. It didn’t even get fazed or surface crazed from these famous and commonly used adhesives

The adhesives were as follows. Tamiya Green Lid thin. Tamiya Yellow lid thick, Testors thin for Styrene, Plastruct glue for Styrene. And even some of the super glues didn’t hold. The only that even tried was 'Bondic" the one that cures by U.V. light! Even Mr hobby Glues, Both thick and thin didn’t dent it. So! When you are grabbing plastic find a scrap one before going to the effort of trying to use it!

I got a handful of dealer plates from a Saturn dealership that went out of business. They are paper-covered plastic. As you note, solvent glues don’t work well but I found that CA does. If you are given free stuff you can always test it and see what works for you.

My favorite bulk plastic is yard-sale sign stock (not corrugated). Less than 5 bux for a large sheet (12x18). It is styrene 20 to 30 thousands thick. Cements with solvent (MEK). Just ignore the hot pink or lime green colors

Hi Ed;

Oh, for sure.Those light fruity colors don’t really cover well for some reason. I did some stuff with the lime green. Took four full coats of primer before Bleed through was conquered!
