Seems like there are a lot of expert panel beaters on this site , Any new panel needs finessing to fit whether it be ford holden Datsun taiwanese replica's . I have fitted all of these so called" crap " panels to my car & could not be happier they all went pretty much straight on and then started alinging them if you speak to any panel shop they will inform you of filler and all sorts of nasties that are present on new cars to get rid of creases in factory pressing as metal will only bend in so many ways before it creases etc, I personally have no problem with filler just the way it gets applied , so to all the opinionated experts with time on their hands to openly bag someone give it to a professional and they will show you how its done , because as an accountant I make a bloody good Truck driver.
P.S The panels are fine just work with them or your alternative is to buy some old ####ters and spend hundreds of dollars of your time fixing large dents rust etc so if there are some creases smooth them out .
