I think the roof looks great as it is, but if you need to caulk it with something I'd get in touch with Sikaflex and see what they'd recommend....household caulk will crack out in no time, and stock silicone would be a nightmare to get right...personaly, I'd leave it as is...it looks nice. Maybe coat the metalwork above the laths with a soft headliner material?
Interesting bus! Just feel that it needs bumpers? dunno,maybe its just me? Maybe some custom made special ones to match the bus? im thinking something shiny,sharp and pointy.... And yes,im expecting some comments about shiny,sharp and pointy...come on then....
Agree it's different and not the usual . I'm convinced it needs something on the front but I'm thinking stainless early style bumpers possibly. Bit too normal. Anyway needs something. It's a bit like when someone has their eyebrows shaved off and you know they look strange but for a minute you can't work out quite what is wrong!
