My front end has bn resprayed and the back end is dull any ideas i was thinking t-cut (yep u got it its red lol)

cant do much bar t cut it really,not consider spraying the whole car?

the first rule of red cars is no part resprays, t-cut can work wonders as long as you do it regularly, it fades again quickly after you tcut, especially on red cars. i had a mate with a red fiesta and he had to t-cut his wing mirrors and bumpers weekly to keep them from going pink.

Try Auto GLym paint restore.

Farcela G3 is fantastic for restoring dulled paintwork, it's a bit stronger than T-Cut but is a miracle product! Has to be used in small amounts and with a damp cloth for best results. Can get it reasonably well priced on ebay If not, T-Cut will do.

Either way, go over the car again with T-Cut colour restorer in the colour closest to your paint - should do the trick

Farcela G3 is fantastic for vandalising your car. if you arent very careful with it you end up with millions of hairline scratches that stand out bad in direct sunlight. i had to spend hours going over every inch of a car that some fool decided to 'polish' with G3. it looked like matt paint, and even a machine polish didnt quite get it back to perfection. dangerous stuff, but very useful for scratch removal.
