Yeah Andy is a nice helpful bloke, but Scaleautomobilia's website inventory is very rarely updated, so you have no choice but to ring him to see if what you want is in stock and order it over the phone.
For gluing bare styrene. Engine halves,sub assemblies and parts that need time for adjustments/alignment. This is my choice, been using it since i started building many years ago.
For parts that are painted,chromed etc, dont require time for adjustment, use it as filler and sometimes use it on window installs. I like to use this, instant strong bond no fogging when using small amounts.
And for windows, lenses, clear parts, gluing various parts on finished assemblies and parts on the body after paint.
