See if you never let yourself try the good stuff then you don't know what you're missing. Floor mats all the way babyyyyyy
Hi

Another foam guy here. Both of my builds were build with 12mm EVA floor mats from the hardware store. I also did some details with 4mm and 2mm foam here and there.
What kind of contact cement will you be using? If you haven't already settled on a brand, allow me to suggest Barge. That stuff dries very quickly and holds really nicely. I've tried LePage, that stuff might as well be water.
Allow me to repeat a tip that has already been said but I think it's worth saying twice. When you start to cut foam, make sure you keep that blade nice and sharp! You'll want a knife sharpener for sure, even if you have the snap off blades. I try to sharped my knife every 3-5 cuts and entirely replace the blade every new armour piece.
