I’m going to try my hand at scratchbuilding a 1:20.3 scale boxcar. I propose to build it using either 1/8’” tempered masonite or plywood. I’ll then cover the sides and ends with scribed .020” thick Evergreen styrene. My question is this ……. what adhesive should I use to laminate the styrene to the Masonite or plywood?

I use 3M #45 spray adhesive for all my laminating. I’ve never had any peel off, and use exactly the materials you’re using–styrene or wood on top of masonite or plywood. You can also use their #77 adhesive, which is supposed to be stronger. I use #45 for mounting photographs, so it’s what I had lying around. It’s very easy to use. Spray it on both surfaces, wait a minute or two, then stick them together.
If you’re using wood, stay away from carpenter’s glue as a laminant. It will warp the side of the car something horrible. I wish I took a photo of the car side where I tried it, as it resembled a Pringle after a short fashion. No amount of weight or pressure would get the car side to lay flat again, so I had to toss it and build a new one.

K,
Could you give some brand names with those? I use super trim adhesive on a regular basis and I think that’s #77. I think it would give alot of laymen a huge help in finding the product.

3M is the brand, I personally like I think it’s the #33 over the #77. In having success with either sray one coat on the woul and let it dry then spray a second cost on the wood and plastic. The first coat on the wood acts as a primer due to the woods absorbtion. I think the # 33 is a contact cement more then just a spray adhesive after writing the above. Meaning the glue sticks to the glue.
Thanks guys. I just checked the adhesives locker and found a nearly full can of 3M #77.
I’ll give it a try.

The 3M is really good stuff, if you are ever going to do a project where you will need a lot of adhesive, Liquid Nails is good. It comes in a tube like caulking and for light applications it goes a long way.
