Ok, I'm planning on putting new carpet in my car. I talked to a local upholstry shop and they said the carpet has too many curves and bend to just put down new carpet. They suggested to buy the carpet kit from Toyota or overlay new carpet over the top of the old carpet with a very good adhesive. Since I dont want tan or black carpet, I have to do the layover. They said they have done this to Supras in the past. My question is has anyone done this themselves? And what is the strongest adhesive I could use? The only thing I could think of was the 3M spray glue. Any info would be great!
