MOT Advisory

[mrgarysmith]

Hi all. I'm no piston head so looking for advise. My car passed its MOT but with the following advisory. Front brake pipe slightly corroded. I was going to spay with waxoil to help slow down the process. I know this wont cure it but was just looking to slow things down and keep the winter weather out. Or would you guys recomend an alternative measure or product.
Thanks in advance.
