I've been watching Boulder Creek Railroad (Luke Towan) on Youtube & it seems whenever there is any scenery to be glued he uses Glue then Isopropyl Alcohol then Glue again all mistings. Am I missing something but I thought Isopropyl Alcohol was used to unstick glue rather than help.

A little lost on this one or am I thinking of something else other than Isopropyl Alcohol for ungluing 

I wonder if it's to do with breaking surface tension, much like adding washing up liquid to the mix when ballasting.

Given how IPA can strip paint and what not I'd be reluctant to do that.

IPA can be used as a surface tension 'breaker'.  Just had a look on the net and there are quite a lot of scientific studies on the subject.

If it's the solvent base of the glue he is thinning the glue in situation to allow it to make a stronger bond.

He uses mod podge as his glue -mixed with water and a blob of dishwashing soap ( fairy liquid to you and me ) I avidly watch his videos on you tube -he is a master at scenery -and I've learnt a fair bit of watching him - then trying his technique  - Defoe worth a look see in my opinion ! Mod podge I get from the Range here in Southport- not that expensive

And some advertising too - note the opening statements re 'easing tension':

Best poured neat, but not onto the scenery.
