Default Best way to fix a crack on a sideskirt

Real quick, whats the best way to seal up a crack on a sideskirt? its a very minimal crack, but i guess theres a lot of stress on the edges.

O.E.M side skirt or fiberglass aftermarket sideskirt? Best way to do it is to either bondo or use fiberglass bondo inner and outer portion of the side skirt and have it repainted.

its polyurethane l-sportline.

i was thinking of using a soldering iron to melt the inside of the plastic.. and then follow up with bondo or a plastic repair kit?

what else have you guys done?

use plastic bumper repair kit from local autoparts.

It's sandable and very strong.

I used it to fixed my plastic cam cover.

i used to manufacture polyurethane products.. What we recommend to our customers was plastic epoxy (like the one on the posted above). There are many different types of plastic epoxies to choose from but I'm not sure which would be best.. Do not use body filler. Body fillers do not chemically bond to polyurethane and will show signs of cracking from stress and heat in time.. You do not want to repair and paint it and find out a couple months later that you will have to redo the whole process.. And do not melt the polyurethane.. Polyurethane processes is a chemical reaction of two compounds joining on a molecular level.. Melting the material will only burn it and cause more damage and weaken it at the same time..

Oh.. By the way, I recommend you make the area rough where you apply the epoxy.. Use a 40-60 grit sand paper to make grooves into the polyurethane.. I recommend this because there will be more surface area for the epoxy to grip on and makes it stronger.. My guess is that the sideskirts have a smooth crack on it.. Am i correct?

the crack itself is not a straight line if thats what you mean by smooth?

its kinda on the corner of the sideskirt like a 90 degree angle. kinda hard for me to explain, but ill snap a pic of it tomorrow and show you.

when you say, make the area rough, are you talking about the crack itself, or the area surrounding the crack?

Rough up the cracked area and alittle on the back face of the s/s.. Basically the areas where you will apply the epoxy
