A pic of the damage would help.

Many creases can be fixed by drilling a series of small holes along the crease then using CA in the holes to bind the damaged area together. Filler is typically for appearance and airflow, not structural repair

Here's a link to some repair work I did on an Eraser Extreme.

I used several different methods, included the CA trick that Mr. Walter mentions.

It depends, difficult to say without seeing a picture of the damage.

When making repairs, strength is #1 thing to worry about. #2 is weight. Looks are only #3.

I would say, if you need filler, use something that is light, easy to sand and not brittle. If it is a smaller area dent, maybe just put tape or sticker on it?

2 component bodyfiller (Unsaturated Polyester Putty)would be the best filler for the job,1-3% hardener added depending on the working temp,you can find the product from any car paint dealers
It;s a spot repair job on the said molded wing crease area
drysanding the crease with #180 grade---->clean--->apply 2 coats of thin bodyfiller--->curing
--->wetsanding bodyfiller with #120#240#320--->2 coats of primer--->drying--->
fine wet sanding primer and featheredging the old paint area with #600 grade wetsanding paper--->clean--->buffing the old paint area with rubbing compound--->topcoating and blending out old paint area....
