Could be the condensation from the aircon.

It's on both sides of car looks not used air con . sun roof open for now

[Rallyz]

Hmm, is it pure water, coolant or oil? And I guess the other thing to check is how far forward it goes.

Had a look again look a lot of thick yellow grease on undertray scrap it off but looks still wet maybe oil on top but it's not water need to use ramp get better look

The underbody wax can be yellow in colour. I wonder if it's been over applied somewhere and now the exhaust has melted it, causing it to run off onto the undertray?
