Don't give up! I have an entire chapter of the Fan-Fold guide dedicated to helping people find Bluecor. Your struggle could help save countless hours of frustration for those who come after.
I'd be happy to ship you a bundle. I happen to live 1/4 mile from a Lowe's that regularly stocks Bluecor. Feel free to get in touch, I'll find out how much a bundle is going for these days, and we can sort out the shipping costs if you like. I don't want you to be left out of the fun I'm having.
I don't recommend cutting the regular foam into 1/4" sheets. That is great if you're going to be glassing it, or sheeting some other structure, but I've found that the thick foam is less plyable, and of course missing the skin that comes with the Bluecor.
So, the options in the guide, and feel free to email me: Hippo@FoamFly.com
or call (734) 528-9446 x1
P.S. I live about 30 Minutes from the Detroit/Windsor tunnel. If you do ever drive down, let me know, we should get in touch.
