My last order from him took some time to come in, but it did and everything was great. I know he has been having internet issues which is hindering his communication as well as running his business I am sure. I have only had one instance of the paint peeling up including the primer, I think that had more to do with my surface prep than the quality of his paint.
As mentioned several times it depends on the situation. plastic to plastic I use either testors liquid glue or Texan and similar types of glues for all other types of bonding that does not involve clear parts I will usually use Bob Smith CA or an epoxy. I have recently started to use canopy glue for any joint that involves clear parts. so far I have had excellent luck with it as it drys clears and is easy to clear if you get any on the part.
I will most likely be picking up the Blancpain version whe it comes out. I am sure someone will come along with decals eventually, i know someone has a set out already, can't remember who, just not fond of the paint scheme on that particualr set.
