Not smart. In future, Heat it up using a heat gun. Most paints arn't really flexable and tend to break when under pressure.
Fixing paint cracks isnt a huge issue though, personally id spot spray it. Provided you can source the colour, a simple light sand, spray and buff should bring her up nice.
If the whole guard needs a respray i can talk you through doing it yourself, which i would recommend considering most shops would want about $500 for that.
