Used this before. It works well when others don't want to blend together.
Happy to be stocked up on this again.

The go to for old dash pad repair
This will melt into that old dash pad foam, and can be shaped immediately. It made restoring the pad a breeze.

Great product
Polyvance makes great products. These rods along with their steel mesh are still holding the floor together in my RZR after an A-arm ripped through it. 3 years strong.

great stuff
If you do any plastic welding then FiberFlex is the stuff to have around, because it is so versatile. You can patch up about anything with it and it really works good with the reinforcement materials, like mesh screening and such. It is a must have item to melt things back together.

Extremely Happy is all I can say.
Extremely Happy is all I can say. I have welded my lower bumper (fiber reinforced bumper) with these rods on my Prostar after a deer strike shattered it into many pieces. Low and behold, someone backed into us and craked the bumper a second time 2 weeks later. i was surprised to find that none of the welds cracked, but it cracked in all new places. I welded it up in all the new places, smoothed it all out, re-painted it again,.. all is good now.
