yup that was me i said use p40 for that exact reason p40 is much harder filler and more flexible.. if i was to it again i would use p40. [y]on another note.......
in the pics above the guy uses P38 isopon over the foam but says to use P40, these are 2 different products, P40 is a glass fibre filler, would this not be hard to work with and sand?
nope bud there was no sinkages in the bumper.. and nope you couldn't see where the bumper strips were originally.. it was a very smooth as you can see from the pics..ok thanks for that
did it ever sink at all? or cud you see where the bump strips were originally?
oh and before i forget, on the front bumper when the bump strip is removed, there are 2 pieces showing that are slightyly raised, i noticed after u rubbed down ur filler that these were still very slighty visible, would it be better to cut them down a bit before i use the expanding foam?
sounds like this is a good way to do it.One word lads - FUSOR.
Plastic welding is good but Fusor is the way you want to go. No heat needed (no melting or warping), flexible (plastic welding makes the plastic a little brittle), much easier to sand than melted plastic, much easier to put on, can glue mixed plastics, comes in various different versions and also has a fine grade/stoppers style version which fills any pin holes and sands perfectly smooth, can be put on with the fusor gun and a spreader, Is sandable within an hour, and best of all no need for filler on top (which discolours over time).
You can take the rubstrips off, buy some plastic sheets from ukplastics.co.uk and cut and glue the pieces into the recess where the rubstrip sits (using Fusor 142), and then just sand them as smooth as possible. Then put a skim of Fusor 114 over the top and sand it smooth and it's ready for primer.
you will have to let me know how you get on with this, perhaps do a little write up so we can see the finished product, ......its something i would love to do to my car too.........[Y]cheers, thanks for that, bought a can of foam today, goin to give this a go!!
Yup bud it will still go on ok as you can see in our pics we done exactly the sameso far i have put the foam on a rear bumper, did that last nite and this evening i have taken the excess off, still to be sanded down yet
after i had done it i realised that it was coming through the holes on the sides where the bumper locates itself to the car, will it still go on ok?
