What adhesive is used on DR 905 valve ports?

[divad]

Is it contact cement or is it something else. If it's something else, what is the appropriate solvent? DR initially responded that they would e-mail the company that manufactures it and get back to me, but it's been a while.
Thanks,
Dave

I would contact Steve Gamble at gamblescuba.com,since he does a lot of their work on the 905s. It is best to call since he isn't the best when it comes to e-mail.
