YHR:

Read the label, if its got Methyl Ethyl Ketone (MEK) its good to go. It'll even stick lexan into the hull for cross-supports!

Is it that tin of medium-dark grey stuff with the wadding-brush attached to the lid? Thats good, is what I used on my German ABS kits, and works a treat. Its also MUCH cheaper and easier to use than the recommended 'Stabilit Express' goo+powder stuff.

To apply it, I sucked some up into a syringe, and then applied. Squirted any un-used back into the tin with no harm done (been using the same tin for a year now) But the best thing (and neatest) - I opened the syringe, and ~pealed~ the dried grey stuff off a day later, so I could re-use the syringe for its next application! Been using the same syringe too!
