Which Flex Seal product?

I want to seal a 1/4" drilled hole in the bottom of a metal gutter. In regard to Flex Seal, do you recommend their tape, paste, Quick Shot, or spray? And should I place a piece of plastic or cellphone first before applying the FlexSeal? Or will the FlexSeal material expand enough by itself to cover the hole?

I know there are products made specifically for gutters, but I'd like to use Flex Seal.

Much thanks.

Since you've gotta use FlexSeal I would use a piece of their tape. Make sure you thoroughly clean and dry the gutter before attaching the tape.

Don't use that crap, it's junk,

Just get a tube of gutter sealer from your local building supply, then you wont have to replace in a few months!

Notice that the label says permanent, they can for a reason!
