What do you mean pushing it up mate?
Cos it's so light, the arm isn't held down as much like the old heavy bonnet. The natural action of the bonnet is to swing open so if it's light enough it will push up, and as a result we have a slighlt push up on one side - solved by removing it....well for me anyway.
Ahh i get you mate yeah mine does the same
Can always put it back on depending on how you want. Getting mine sprayed gloss black.
