I have all of my carpets remove and i am ready to dye. My only question is should i remove the foam molds on the underside of the carpet; or is it fine to leave it in. I really dont want to cut it out. Carpet is out of an FC. I am dying it Black.

 

You could probably leave it.

But if you wanna remove it and have fresh new foam check this out

I don't think you need to remove it.....a few supra guys did it and left it on there.

 

i dont know how you are dying it, but whenever i dye carpet i wet it first to make sure it comes out even
