I finally got to start working on my Javelin. I just pulled the old carpet/seats out of the car to make sure everything looked good and do a little cleaning and replacing. With that in mind I have a couple of questions.

I would like to keep the interior noise as quiet as possible and keep the floor as solid as possilbe. Would it be best to spray the floor with any kind of sealer or sound dead-ing product or just use the padding?

I would also like to put a roll cage in the car, but don't want to cut the interior up to fit it. Does anyone know the best product to do this?

Thanks,
Aaron
