hey i'm reparing the rusted arches on my ford transit by using fibreglass arch ends and blending them in. The arches will be bonded onto the old ones and will then need blending in. What filler is best for this? What else do i need i.e hardener etc etc?

so bored in this weather!!
is it just me or is it very frustrating?

 

bump

 

Best filler i've used is called easysand from halfords

 

Upol is the best imo
