My car has got loads of parallel lines all over the paint work. It looks fine until it is under the sunlight and then it looks really bad as though it is full of streaky scratches. I polished part of it and tried a bit of paint renovator too, but when washed again you could see them right away. I went down to a local body shop and they said that it looked like it had been through a carwash all of its life, which is probably true thanks to the previous owner. They said a high speed buffing for £150 would get rid of most of the lines. I reckon a dose of scratch-x would get rid of some, but they would surely reappear again. I want a permanent solution, would a high speed buff achieve this? or would it look brand new for a month and then go back to normal? Would it not be possible to just respray the top clear coat laquer? Is £150 expensive and what can I expect? Any suggestions as it only looks bad in direct sunlight. Thanks for any replies.
