That yellow one with the 1UZ had em done and I have seen a few others around.
If your welding in metal, it shouldn't crack. If your filling it with bog as some panel beaters do, then it definitly will. Most panel beaters hate this kind of work because it is hard to get a good finish without using a heap of bog. If your guy is an old school "panel beater" and not a RnR insurance specialist, then he shouldn't have any problems.
Same Colour Stew??
