Hi Guys
I have a Alloy hard top boat just below the windscreen i have some paint bubbling.

I am assuming their is some corrosion going on underneath and wanting to treat it.

At this stage i am not wanting to pull the screen out if i can avoid it.

I was thinking of scraping back the bubbling paint and then giving it a good sand / clean up and then prime / finish coat.

Am i on the right track?
What sort of primer would people recommend.
