poor bloke... theres nothing worse then people milking it... the thing is that you get your insurance company to get them to pull a finger out, and then when the job is done get them to warranty it and give you some sort of a guarantee against cracking or whatever the concern might be and if your not happy with it then just tell the insurance company and let them pay/ deal with the problem...
it happened to a friend of mine when he had an accident, they milked it for ages then when it was finished he had overspray everywhere, on the tires, the inner guard liners they totally f**ked it... so he demanded them to do it again so f**k em dude get em to hurry the hell up
