How to repair a small crack in atv plastic?

Ok a couple days ago I was changing the oil for the winter in my 2007 Honda Recon and it all went good until I was getting up after filling it back up with oil and I got a little dizzy (I have high blood pressure) and I fell into the left rear fender and put a small crack in it, it wasn't that noticeable at first but it's already spread to probably 4 inches long… Can anyone recommend a way to fix it so it will look stop cracking but also decent? I've seen redneck repairs that are not only God awful looking but they also don't work, don't know if someone just didn't do it right or if it just doesn't work so I thought I'd ask the pros.

You can get a plastic welding kit. It's a high temp heat gun with different, removable tips. Then you just need to determine what type of plastic it is and follow the instructions in the kit.

Get a prescription for high blood pressure.garlic oil will also lower blood pressure a little.

Get the plastic weld kit for next to nothing, try it, if you fail farm the job out to a professional with a nitrogen gas shield plastic welder.

The more elaborate kits will have a glass reinforced low temp plastic that a beginner can glue a difficult plastic crack solid with.

I think I would probably use fiberglass and epoxy resin on the underside of the fender.

3 coats of resin with 2 sheets of glass in it ends up pretty strong

Contact you local Honda parts dealer and see if the sell compatible glue for the type of plastic that the fender is made out of. If not a new fender shouldn't be too expensive.
