Hey! Shut up about DIY repairs, I've got a holiday to pay for! :laugh::laugh::laugh:
When we weld repair sections on its usually because a car has failed its MOT. We would be happy to tidy them up and fill the area but...
If was buying a car I'd prefer to beable to seepatches etc. had been welded on properly rather than wondering what as under some filler. Keeps the cost down for the customer too.
Any time we have welded patches on Micra sills we tidy up the weld a bit with the grinder then splash a (thin) coat of stonechip on to stop it rusting as fast.
We have fitted a few full sills on Micras. At the edge that joins the bottom of the rear wing we have ground the weld right down and primered the area. Its up to the customer whether they have it hidden or not.
I'm always suspicious if someone has filled or fibreglassed this area, especially on a Micra. There are too many Micras out there where if you scratch away the filler Tony the Tiger will be staring back at you! :laugh:
(Please note, not all filled or fibreglassed Micra sills are dodgy, just the ones I have seen! Tony the Tiger is a trademark of Kellogs)
