I am looking at using some Loctite PL 300 for a quick project. It states it can be used on Polystrene. Would it be safe to use on a lionel tender?
Formulations for body shells varied over the years, mostly within the styrene, polystyrene and ABS families.
You’re probably safe, but to be sure, first apply the Loctite in an inconspicuous place and watch for any adverse reactions.
