Hi
I have some wooden sash windows needing painting.
How much is a correct price for 1.5 x 1 meter window to paint by a painter?
Im in the east midlands.
If i do it myself, do i sand, prime, paint and then add putty after they are painted?
Ie putty is the last step? It goes on top of new paint?
If its not raining, is here a oroblem in doing these in november?
Cheers

Generally the "static friction" is extremely high, as the relatively soft stationary tyre has plenty of time to physically deform around the rough road surface and "mechanically" grip that surface. As soon as it starts to revolve, the effective friction co-efficient falls dramatically. The as vehicle speed builds, dynamic effects, such as windage (or "waterage" if it's raining) start to occur, and in fact, the tyre contact patch changes shape as the different loadings on it wax and wane (ie centripedal acceleration of the tyre carcass vs normal load from the vehicles mass minus any lift forces (most road cars have positive lift co-efficients btw)
