A larger dent section repair ,on the engine cover of a vespa scooter, ( time to silence my critics) as you begin to under stand, dent theory and practice what i have shown in these free tutorials , by repairing smaller dents and dings , you can move up to bigger damaged panels. the rules are still the same,!!
