Depends how extensive you want to get into it.. I would tape it off.. And buy some body filler... you could use some bondo.. But it's a serious pain to sand if you have never worked with it... Then you can try to match it with some paint..
Go to an auto parts store and pick up some J.B. weld water weld white putty. Mix small pieces together and fill using a putty knife to get it flat as possible. Once it's dry follow up with 500 grit sand paper. Wax and it will turn out nice. Repaired holes in mine that way.
Ouch, sums it up nicely.
I'll give the J.B. weld a try. I've used bondo before. What a pain.
Thanks gang. I'll yet you know how it turns out.
Happy trails😎
