Resealing the hatches
I was going to scrap off and use a wire wheel on the old cracked sealant, clean with denatured alcohol, then apply Dicor lap sealant. Am I on the right track?

I just use a heat gun (on low) and a plastic scraper to remove the old caulk. I would not use a wire wheel or brush, it could damage the surface.
If the old caulk is solid, I don't remove it. I just remove the loose stuff, clean well and apply the new sealant.
I use acetone to clean the surface,
Thank you.
I forgot to mention my roof is aluminium.
