Oil pan gasket vs rtv

Was looking up a request for oil pan gasket yesterday for mid 10's Chevy Malibu. 2.0L DOHC turbo or 2.5L DOHC non turbo. Oil pan gaskets do not exist. The customer was at wit's end. Told him that black silicone is what is used. Would think that there could be a market for some kind of rubber gasket, similar to what is used in many tranny filter kits, for those who simply don't want the mess of RTV silicone.
