Hi, been searching for what sealant to use after welding new metal into my campervan and Sikaflex Polyurethane seems to be highly recommended but which type is this, is it Sikalfex 291 or 221 or soemthing else?
I want to be sure its safe to use on zinc oxide painted bare metal and can be painted over once dry as well.
Cheers
