what do you mean by smooth it more? if your on about the wiper hole then no p38 wont do you will need to weld, if you on about smooth the lones on the bumper then you could use p38 but plastic filler would be better
lones on bumper? what is this you talk off, but yes was talking the wiper blade hole where i'v put the rubber bung.
swage lines sorry :embarassed:
yh the wiper hole will need flatting and welding, just filling will not work. if you dont want the weld it you could hammer the raised bit flat, then get a piece of metal thats bigger then the hole, then bond that bit of metal behind the hole then fill over that. this way would work but is only a bodge, welding FTW
