Where to purchase caulk for dash and arch

[STEELE]

I have a 2005 280SD. I'm looking for replacement sealant/caulk for the dash color is Zephyr #940 (Bostic was the manufacturer), also, Arctic white for the Arch # 960. Apparently these products are discontinued. Anyone know of a replacement caulk and where to buy?
