// Frame corrosion

As with the PRE Cub models, this is STILL a BIG problem.
The Cub has a colour matched plastic cover over the rear part of the frame, just where the older models used to rot out.
When buying a Cub , Always check underneath the rear wheel arches , as they DO STILL ROT !!!!
This IS an MOT failure.
To prevent any further corrosion, Remove the rear wheel.
Wire brush the pressed plate & surrounding area , then preferably prime / undercoat the area, to avoid future damage.
I always coat with grease, for an extra precaution!
