hes on about the inner wing rail where the inner and outer wing are spot welded together



theres a product called soft edge foam you can buy from any half deecent spray suppliers mate , its like a 5 mm foam tube

ask them when your there for instructions how to use it but you basically stick it to the top corner edge of your wing ,and it dosent leave a hard edge when you spray to it hence the name simply mask to the back of it
