You need to sand the slick skin off of it so the resin will stick. They didn't do that on the two tunnel pieces and it's loose.

 

I believe they make both a lined and unlined version of the foam. In some cases, the lined stuff can be peeled off, or sanded as fmcokc noted. Epoxy resin is a must, as polyurethane will melt insulating foam.

 

[QUOTE=sexyicky;1524862]Just finished this splitter design with the help of a friend. Its 1/2 birch and runs under the oil pan. However, I want to try something new so I purchased 2 sheets of 6mm Alupoly. I will report back how it holds up.

What material/product is that splitter fence that you bolted into the birch for support?

 

That's "paver edging." Find it at whatever your local big box store home center is (Home Depot/Lowes/Menards/etc).

 

I've seen some splitters made of alumapoly... it's pretty flimsy.

 

Another Shakydog splitter panel in production. Getting ready for Barber in a couple of weeks.

Have a few extra tunnels. Going to make another one for the "new" car as well after the Barber race.
