Before Gluing it sometimes helps to clean the surface with methylated spirits. This is also known as denatured alcohol.

Bonding Coroplas / Corex
Many years ago (2002) I was making and selling many SPAD aircraft kits and I had very little success with flashing and CA which was the recommended method at that time.
My solution was to contact an adhesive manufacturer in my local city and challenged them to bond some sample corex that I sent them.
Within two weeks they returned me a sample bottle of a CA they code named SF100 (Now available from 3M), along with my corex samples well and truly bonded, in fact one of the planes made back then with SF-100 is still flying today without any problems.
I, like you test the bonds to destruction and in all cases the corex surface was ripped to shreds with large chunks still bonded to the other test part.
The method used to create such a strong and lasting joint only requires the corex, (both parts), to be cleaned with methylated spirit and allowed to evaporate prior to putting spots of adhesive every half to three quarter inch onto one surface, place the two surfaces together and apply even pressure along the length of the join.
I am aware that 3m Scotch-Weld SF-100 is not a cheep adhesive but it really does the job as long as it is fresh and stored at low temperature out of direct sunlight.
Hope this is of interest

They offer their corrugated plastic "Corruboard" in many thicknesses. Look at the top of the page for the various boxes that are made with it.
Coroplast scoring Video
Youtube video showing how the Corrugated plastic can be scored before bending using what looks like a dulled pizza cutter. I use a roller that I bought to repair some screen windows. It has 2 size wheels.
This information is for general knowledge. Using non tested materials can be dangerous. If you build a Coroplast boat (or any other project) be careful and make sure you test and use your boat in safe waters with appropriate personal flotation devices and backup help. Using power tools can be dangerous be careful and be safe.
I started building a Coroplast folding boat. first step is a model but I have my materials.
