...only purchased it this morning Martin......

I searched on Gorilla Glue.....then found a number of alternative brands of PU glue.....& they all tell the same story for strength...drying time, 100% water resistance when cured....foaming & expansion during cure & the use of a water spray mist prior to the application of the glue to aid the curing process......etc etc......
They also talk about the ability of the glue to penetrate the wood grain structure by long chain adsorbsion.........with the result of providing a very high end grain to end grain joint strength
The real advantages of using PU adhesives for model hull planking & wooden boat construction appear that is a 1 part application...& hence no mixing

...and it does not result in the brittle joint of epoxy resins
For me....the proof of the pudding is reviewing the images from Mick in the Wide-A-Wake thread....

...& seeing the wooden components assembled & glued without pins & nails etc......brilliant work
The reason I chose Sika PU ...was simply availability here in Australia ..........Derek
