I think Mista JC has a molded lip on his coupe. Dunno if he did it himself but its worth asking.

ya when sanding bondo you reach air pockets that need to be re-filled with more bondo if not sanded out smooth.but then probably by that time youl have a dip and need to fill it back up..
as long as you dont flex it to much putting it back on,ect it should last..we use polyester filler on bumpers at work and its fine..just primer it,block it then paint it.
iv done so much body work its not even funny how much bondo sucks..lol but just spend some time with it sanding,filling.sanding..eventually itl turn out good.

edit;if the holes are air bubbles and not just where the bondo seaped through the cracks then you should mix it with a folding like method instead of stiring it..that causes air pockets inside the bondo*cant see it but when sanding out you will see.

hey thanks for the info. Where can I get the polyester filler that you are referring to? is it a resin? would i be able to get it at, say home depot, lowes, etc?

i thikn you can get it at home depot. i saw it before. i also believe walmart has them also. but yeah, bondo isn't good for lip because when you hit something, it'll crack for sure.

ya check out pepboys,advanced ect..
we use EVERCLEAR at work. but when i molded my body kit to my car i used fiberglass matt and resin..then sanded that down then layed some kitty hair resin over top of that.sanded that down then bondo.
its a long process and lots of sand paper..haha

edit-
also the longer you leave that bondo sitting there,the harder its gonna be to sand..just FYI

Let see hmm.. poly-urethane on polyurethane, First scrape off all that bond or crack it off because it will anyways on its own. Evercoat makes something called "puddy glaze" which is very "mud-like" usually used on bumpers to fill in dents. The other thing is your going have to re-enforce the whole rear side of the bumper with fiberglass to reduce flexing. There is also plastic weld but it depends how good you are, I used this on my bike fairings but I failed at it. I molded a rear lip using the puddy alone on my hatch but front bumper is a different issue. Please buy your materials at a automotive paint store. GoodLuck with your experiment, you will learn as you go.

Basically, you are using something very flexible, attached to something very flexible. On top of that, you have a BIG gap. At the very least, i would start with plastic welding them together so they atleast kind of flex like one. Then i would fill that gap up, fiberglass would be a good option compared to any filler to actually fill the gap, but will most likely crack.


If it were me, i would either plastic weld. screw. or rivet the bottom piece to the bumper. Then, i would use a think piece of aluminum to fill in the gap. Attach that with screws. Then use fiberglass impregnated filler to start, finish it up with as little body filler as possible.

That still has a good chance of cracking, less than just using filler (of any type).

Thank you. I already took all the bondo off. It wasnt going the way I planned.
There was too many little holes and wasnt even and stuff.
When you did your rear how did it turn out? I might just do what you said.

why would u mold a lip on ur bumper if ur car was that low?
I dont get it. Well. The reason why I wanted to do this is because I thought it would look cool and no one has done it.

because that's what the cool katz do. :kenny:

I got rid of the bondo. There were too many holes to be filled in. It was so annoying. I dont know how the fiberglass is going to work filling in the big gaps.


Thanks guys for your input. As of right now I have no idea which way I want to go. But whatever way I do go I will let you guys know. (;
