[Old Jock]

Well, I finally gave up on waiting to have the chassis steam cleaned and degreased it myself with good old, old-fashioned, Gunk. What a dirty job, but what a good job the Gunk did. Now all I need to do is find a day without rain so I can grit blast the chassis.
Like Car Photographer, I have been thinking of what to do about a grille. I quite like the mesh grille which he is considering but have also tried this. What do you think? I know it will make the aperture a little smaller, but nothing that can't be compensated for by using twin electric fans I think.
