filling holes in deck - what tape to use on bottom?

[LookingForCruiser]

OK one last goofy easy question that probably everyone knows the answer to.

When I'm filling a hole in the deck (e.g. overdrilling, fill, then drill smaller hole, so no core is exposed), I'm supposed to tape from the underside, and then fill with thickened epoxy, let it cure, sand it flat, and drill the smaller hole through the middle. Easy enough.

But what kind of tape do I use on the underside of the hole, so that the thickened epoxy doesn't stick to the tape itself?

Just some good ol' duct tape.

The epoxy will stick to the tape adhesive, just like the tape adhesive is sticking to the area around your hole. It will peel off either way.

I use electrical tape, it leves the smothest finish.

You can back it up with cardboard and duct tape if it is a big hole.

I use masking tape. Most of the time it will come off clean (however if you get epoxy on the other side of it - it will embed itself and become laminate). No big deal usually - so there is a piece of epoxy-paper stuck to the inside, it is normally covered with something or inside a locker anyway.

Looking,

I use the blue painters masking tape. It has worked well for me.

OK, I can now officially tell I was overthinking this problem... thanks for all the replies!
