I done the same as you and mine looks good too . One thing that did concern me was there is a piece of insulation in the engine compartment that runs from halfway down the strut tower to underneath the brake booster that butts up against the firewall near the plate. I pulled the corner of it up and it was soaked . Looks like the rain runs down between the bonnet and windscreen onto the insulation then has knowhere to go which is a bit of a worry. It might pay you to have a look under the insulation to see if any rust has taken hold.
