hi just wondering how its done, just plastic welded or what? and is it ok if i use an 8v bumper or should i use a 16v, are there different types of plastic, as my 8v bumpers seem more solid that 6n2s and i dont know if they can be plastic welded together because of it.

I'm going to be doing a set of front and backs soon mate and yeah there the top part of a 8 or 16v plastic welded fibreglassed and fillered together quite a lot of work to get it right but looks awesome
