Hi Alan,
I took my snorkel to a local body shop.
Nothing fancy.
He told me a good clean with some plastic tolerant solvent
Then a wash in warm water with a touch of Fairy liquid washing up.
No rubbing down
A couple of build primer coats, don't know how many though.
Then the Silver, don't know if it is ordinary silver for car body repair, or a flexible silver.
Sorry.
Then I went up to West Coast 4x4 in Banks, Southport, and Paul and his crew fitted it for me.
Gra.
