Molding Rear Bumper Questions Options

[DSToyo]

i am considering molding my rear bumper of my kit. i have never worked with fiberglass and wanted to know how hard it is and is it worth it. i have heard that the mold can crack when being tapped in the parking lot or even weaken with the canging weather conditions. i guess my question is, is it worth it when i am going to get a paintjob/how easy does it crack/how to repair if cracked?

Thanks for any feedback possible

We molded one of my friends sideskirts and have to say it was a lots of work but worth it. Saved lots of money and even after a year theres no cracks. But you def have to get some knowledge before doing anything. Its not hard even at first time when you just got someone to tell you how to do it.
