Bondoing exhaust tube question.
Since my bike is sorta ready to ride, I'm thinking of painting the exhaust tube. Since, my weld are the prettiest weld compare to anyone here, I like to paint it flat black. But I want to smooth out the weld with bondo, and I really don't know if bondo would withstand the heat from the tube. It looks like bondo would be ok up 180F. DOes anyone know if the exhaust tube ever get that high?
