SD Bumper cover attempt

So, as finding a decent front bumper cover shipped to me is becoming a battle, ive decided to try and fiberglass in the area that is ripped and gone.

Has anyone attempted this that could give me some good advice?

If I find some free time when its not snowing or blowing at 100 mph, ill try to get a couple pics in place.

My plan at this point is to build a base on the inside of the covers with fiberglass and layer in the area that is missing with a few more layers and then use a fiber hair bondo to smooth it out.

Sounds like its possible in my head, im just not sure how well it will hold up

Are you familiar with glassing?

I wouldn't use bondo (I just have a personal thing against it).

Good quality West Systems resin makes a hell of a difference when working with glass.

As for sticking glass to plastic.... I don't know what to tell you. I've never tried. I've seen chunks of bondo ripped off my freinds car and they had rivits in the plastic to try to get it to stick. It seemed to hold fine till he hit a deer.

Deer do that!

Im not sure what im going to do at this point.

Someone told me of a plastic repair kit, using mesh and a liquid resin type filler.

Ill have to try and find what the product is. As for fiber to plastic, ive been told it works, just not a reliable fix.

If it doesnt work, im not out much beyond material cost, its a hole in the cover right now, worst case is its a bigger hole

One thing i recently learned is that Bondo requires a properly prepared cleaned and primer'ed surface to stick to - I thought it was supposed to go directly on plastic or metal, but it isn't!

It's designed to adhere to an intermediary primer - crucial. If it's not, it will chip and come off as many people experience.

All cars use body filler / bondo from the factory, nothing inherently bad about it.

I just remembered... I have glassed to plastic before. (does that mean I'm getting old? )

It was cheapo chinky motorcycle plastic. I used West Systems fast dry resin. and I gouged the old plastic to give the glass something to really grab hold of. It worked pretty well. In fact I belive it is still on the road today (3 years )

The glass work was around the bolt holes on the fairings; probably more stress than a ding in a bumper would encouter.
