Hi Brian,
Yes I have been caught also. Found myself beside the road using a sponge to get the water out of the footwells.
Just luck I have aluminium floors. Have just made a note of putting some rubber plugs in.
Park on the side of the road and let the water run forward and out the plug??
I have travelled over 10,000m ( 16,000k) since last November and have just painted my Cobra after driving around in Gel coat.
My painter made the comment the other day I will probaly now become a "sunshine pilot"
I will until the 'new' novelty wears off.
Don't envy you cleaning the Cobra there.
Bernie
