Repairing missing fiberglass diffuser. Need help!

seventy5 · 09-04-2012, 09:09 AM

I got the hamann rear diffuser not long ago and decided to put them on. But I ran into two problems after cutting the bumper. 1. There is a 2inch gap between the diffuser and bumper. I think I can fill that gap with weatherstrip. But don't know where to get it. 2. In order to make the diffuser sit perfectly, I have to cut the side corners. Now I have a missing piece on each corner. Anybody have any idea on how to create that piece to go on top of the bumper? Thanks

I don't have a picture of this diffuser to know its final shape. Do you ? That might help us diagnose the next step for you.

If this piece is made of FG, then you'll be able to graft more fg onto it and make the missing ends.
However if it is plastic....things get more costly within proper plastic prep and materials.

Are you certain that the kit was complete ??

Yes. It is a complete kit and it is cf. what is the first step of crafting the missing part?

The piece in your picture looks to be in grey primer. Did they primer the CF ?

I'll need an image of the final part to guide you further.
