Guys I used to sell two methacrylate products by Permabond, both were superb but just a word of advise, they are not wonderful when glueing wood/ply as they contain a self etch chemical which tends to get absorbed into wood and then leaves the bond weakened as a result, it bonds composites, steel and aluminium superbly, just not wood - as a result its no good for most former work!

It does tend to heat so if you are using it to glue parts to fuselages you will see over time quite a surface 'ripple' where heat and shrinkage mark the fuselage, one final and more important note, once the joint is made it MUST NOT be disturbed until cured, the bond has to happen without movement otherwise the strength will be dramatically reduced - I spent a long time speaking to manufacturers around this topic. With 9462 you can re-position the parts until it becomes fairly tacky without any issues of strength being compromised.

Here is a link to the product I mention (re-branded now).
