Outer Limits 4x4 Board

So i've cut and welded in metal for my rear wheel wells but because i used a lot of the original metal i've had to split it open to stretch it properly.

Now what i was thinking of doing was to get some plastic sheeting and then line the whole underneath of the wheelwell and so it covers up those holes and also acts as a mud guard hanging down at the back to.
Anyone tried this and not had a problem of mud and sand collecting up behind the plastic? I would fiberglass over the holes but i had some there before on a rust hole and that ended up blowing out because of the large amount of fast heavy mud being flung at it
Or should i just weld some more sheet metal over the top and give it all a good heavy coat of some type anti stone chip paint underneath??

i'd say go for your second option that way it is solid and shouldn't need to be fixed later on down the track.

Weld it up , then wipe seam sealer on the welds , then spray black proof coat or stone guard in the wheel arches , be careful to clean everything properly to make sure the paint binds to the inner guards , Cheers Paul

Ok i'll go the welds cos of the strength like you've said. Is this seam sealer just sillicon filler or something that makes a better bond?

For those thinking of doing a virtual lift heres a pic of how much space i've gained its atleast 20cm from the 32 inch tyre when its in there.(didnt have the camera handy when i fitted the tyre )

There are many brands of seam sealer and one of the common one's is Dripcheck , can be sourced from automotive paint suppliers , the stoneguard now comes in a pressur pack , might be a chaep and easy way to apply it , Cheers Paul.

Weld it up then use stoneguard on the inside and outside. The stoneguard won't allow for water to sit.

If you attach plastic its just another place for mud to build up, moistuure to sit and rust to start.

just wondering, is virtul lift where you cut the guards and all?

Ben

Yeah virtual lift is where the guards are cut and the wheel well is pushed upwards to create room for the tyres. Keeps the COG down low cos the only real lift your getting is from the extra tyre height
