howdy folks,
the question is the header. im searching for a glue that provides a good strong bond, has some 'adjustment' time and won't fog the glazing. any help or experiences will be greatly appreciated.
regards. dean

For glazing work I generally use Micro Krystal Klear. It's a PVA type glue and sets very very clear. It can be removed again with a soaking in water.

Another useful material for gluing clear material is Johnsons' "Klear" (sold as "Future" in the USA). It's very different to Kristal Klear despite the similar name, being basically an acrylic-based gloss varnish. Not only does it not fog clear plastic, it actually enhances its clarity - painting or dipping glazing parts with Klear can improve their appearance a lot. It also loses virtually all its volume as it dries (like most acrylics) so you don't get blobs or brush marks.
The disadvantage of Klear is that it has very little "tack" before it dries, so parts need to be set up carefully then left to dry.
As EP says, Krystal Klear is a very useful adhesive for clear parts. It does form "blobs" unlike Klear but this property can be used for filling in corners + gaps where glazing doesn't quite fit properly. It can even be used as a glazing material on its own for small apertures (such as cab windows + spectacle plates on steam locos
Both replies above are excellent although i'd favour Alan's recomendation of Krystal Klear i've used it for years for attaching glazing & in small apertures
so then would you knowledgable fellas be able to recommend a glue for brass window etches. would the two suggestions above still be suitable for metal? Dx

Hi Dean,
What are you glueing the brass etched windows to or are you using clear plastic glued on to etched brass windows ?
Brass to brass I use evostick impact for most stuff, superglue paste for very small parts. Brass to glazing I use kristal klear.
Handy trick for tiny parts btw - tiny bit of light glue (eg PVA) to glue part front onto cocktail stick, superglue paste on back of part, attach to model, hold until it sets and remove stick. The superglue join (if set properly) is much stronger.

i wish to glue the ratio 'n' gauge signal box, brass window etches onto clear plastic. i'm uncertain whether kristal klear would make a strong enough joint.

I havnt glazed my brass etched windows on my Ratio signal box yet Dean but the window frames themselves i used superglue to attach them to the plastic, i'll either use a tiny spot of superglue on the edges of the glazing or Krystal Klear to individually glaze each window opening ;) when i use superglue near glazing i play a fan over the model while the glue dries it stops the superglue fumes glazing the glazing, heres a link to the tip i left on the forum

My signal box ready for glazing ;)

Superglue fumes tend to fog glazing material - and annoyingly they can do it over time.
