No it will always come back IF its in the plastic and you just primer and paint it. If it didnt have the cracks before she bumped it, its prob just in the paint. So you might not need any filler at all. Just dont pile on primer and paint thinking that will fix it. IF its in the plastic AFTER you sand all the primer off, then you use some filler after Ving them out.
When you put the first primer on, just put on a couple of light to medium coats. Most times it will dry 'fuzzy' because of the plastic fibers. Scuff off the top coat of the primer with 320-400 paper to get the fuzz off and make it smooth. If you can, try not to sand clear thru. Respot the primer as nec and it wont fuzz up again, then put your paint on. It usually only fuzzes up with the first coat of primer on the bare part. Make sure its all smooth before you paint, it will show thru as rough. It may not feel it, but it looks like it is. Again dont bury it in layers and layers of primer...it ONLY needs to cover the entire part.
