AE86 in the winter

Agreed with Uzelac there, good underseal (truck bed spray works well), undercarriage sprayers are available from Karcher to clean the underside of your car whenever you'd be cleaning it.

Behind rear lights, inside front wings (fenders), front chassis legs to inner arch, rear seat pockets, A pillar behind the wings and along the sill.
A good injection of cavity wax will work wonders too, just a little messy!
