Cheers

If you have a look on the underside of the part there will be a manufacturing mold mark which will tell you the part number & what material it was made from. Quad panels are more often than not H.D.P.E (High Density Poly Ethylene) as it is known for its flexibility. To effect a good repair "V" the damaged area out & make 100% sure you use a rod or sliver of identical material, preferably from the same make of bike as different manufacturers use slightly different materiel recipes for there body work - if you can peel the "weld" out once it's cooled the materials are incompatible.

be prepared for the 'roll' to not work
I've had better success by using a grinder with a thin blade to remove a few small slivers/sticks from an edge that cannot be seen once the plastic is refitted ( under the seat is always good for surplus )
thoroughly clean it to get rid of dirt and dust, oil etc, and finally I wipe it down with iso ( plastic pipe cleaner )
Build a jig or lay a sack of sand over a small table so the welded area is well supported, and use a roller over the weld while it is still pliable, even your biggest deep socket will do, just flattens it better and thus easier to 'finish'
