Hey guys, i just bought a 2nd hand bumper and im looking to fix it up.

Now on the bottom of the bumper there is a crack that goes right through, i was thinking of just using some body filler to fix it, but i think the filler will crack when the join flexes.

I was how ever thinking about glassing the back side of the crack (on the inside of the bumper) to give it strength and body filling the outside.

Do you guys think it will work alright?

On the bottom here you can see the crack.

Whats it made from? if its plastic you can get it welded and provides a better/stronger more flexible finish than glass. Look up plastic welders, most of them repairs motorcycle farings. After the weld you can then niki up what little parts need it and prime/paint away.

To be honest i would rather something i can just do myself, thats why i thought of glass.

Edit: Yea its made from plastic.

I don't think glass will stick properly, and will also have different flexibility, so it'll just crack again in a few months anyway.

After talking to MR SPL and seeing this link,

I think i might plastic weld it myself, i mean ive got nothing to lose.

I saw that video earlier, so im thinking i might try it, now ill just need some strong plastic to fill the gap.

Its not that hard, just practice on scrap first.

I got a butane iron with a knife attachment that will work well.

Anyone know what i can use to melt as a plastic filler? Obviously im after something from a hardware or automotive store, otherwise ill just improvise.

I'd probably be using a temperature controlled iron so you can set the temperature properly or you'll probably just burn it, rather than melting it.

I can change the temp via a dial so if i do it carefully ill be fine.

yeah, just a cheap black plastic toy... sure a vinnies store or a 2nd hand shop would appreciate your money more than bun-gings!
