so while putting the bumper on, I mise just take the guards out to check the rust etc. mainly clean the Dirt and Leafs at bottom of the guards. and also surface rust killed primed up the door hinges.
While Everything Looks super clean, There are some surface rust at the draining exit area. The reason for this mainly is because of shit design. There are three lays of metal and it is sealed with these factory sealant.
So,bent the last layer slightly, Sand, rust kill primer, Epoxy enamel paint.
The other side I probably pushed bit too hard, found a small hole from a sealant came off. looks very factory, so the sealant covered up a hole from factory?
Anyway, again sand, rust kill primer, epoxy enamel paint then sealed it with urethane.
Also, sanded the bottom of the front wheel arch to check rust, found only steel. so that's good sign.
Fish oiled the bottom of two guards ,and Put everything back. the new bumper looks shit? or I need to get used to it.
