I am interested in what type of wheel and filler also. I have a wheel that was bent on both inner and outer lips and I want to get straightened but there is the risk of them cracking and then I would be able to weld it and then take it back to be finished at the wheel place. I have had them straighten a wheel I purchased bent before and he does a very good job but he does not weld and it costs more if it needs it as he takes it to another company. He did not crack my wheel but there is always the risk.
