drivers view on tiger 1

Ye, agreed, leave it be. The glass in cupole's will often be periscopes, so i think this is why people feel the ned to tint them. The drivers block is just a thick piece of glass.

My opinion?  Leave it as is:  The gloss would exaggerate a 1/35 piece of glass' finish.  As to any blue tint -- the actual glass had none -- modellers feel compelled to add this to mimic the tint that sometimes appears at different angles.  For your driver's block, I'd leave it alone.
