Gluing HDU and prices

[Signsup]

Hello,
We have glued HDU panel together in the past, but it has been a couple of years. We want to do some double sided oval hdu signs that are two inches thick. I figure doing two 1" inch hdu signs and gluing together is easier than a two inch hdu sign. All my router bits are only two inches. What glue do you suggest? These ovals are 36" x 60" I see people use white gorilla glue but i only see where you can buy it in small bottles. Also, since we do not do a lot of this I was wondering about pricing. The signs are two inches thick 36" x 60" Oval. A raised block word in the center with a raised border. Painted two colors. Nothing too complicated. I am curious where others would price this? Any help with the glue or insite to pricing would be great!

Just out of curiosity, how will the sign be mounted?
Do you have any sketches, drawings, etc. to share with us ?

I've only ever used the brown Gorilla Glue that expands with a light misting of water beforehand. My experience has been very positive, but of course a sign that size using this glue will require a bucket full of clamps or heavy weights to keep it from warping as it expands. I have also routed out circular holes & channels half-way through the backside of the HDU so the glue has a place to expand.

We double sided HDU same way, two 1" faces and usually a matching panel of ACM fpr the middle of the sandwich. We use a polyurethane adhesive and a few screws if possible. You can also build in the mounting hardware when putting the panels together.

Using some ACM in the middle is a good idea. If I decide to do one two inch piece and buy a longer router bit to cut the perimeter, are there any good tricks to getting registration to cut the other side? I can print registration marks on styrene and place the styrene on the non engraved side after I engraved the other side and cut out the oval.

Are you using Gorilla glue? If so, which one? If no, what other polyurethane are you using?
