Hi there, just a quick question. Im modding my console for a double din headunit. Ive opted for the 'i like to make things harder than they need to be way' by moving the heater controls down so I can retain my airvents. Question is can I use fibre glass filler from a tin and just bridge the gaps to hold heater controls to new position? Or should I use a fibre glass repair kit? Oooor should I plastic weld (what sort is best and how do i smooth it down after)? Any help would be greatly appreciated.
