Quick floor sealing question
Been lurking for a bit, getting into the thick of a 98 BB TC2000 conversion. I pulled the seats and floor, cleaned and treated, put down primer and paint, and last weekend hit the holes with PU sealant. Current state of things:
I also picked up a roll of this and have started covering the sealed holes with 1" squares of it. ~100 square inches in and I'm questioning myself. It's taking forever and making the floor awful lumpy (material is ~1/16" thick) which will complicate things a bit when insulation goes down. Should I scrap the tape and rely on the sealant? Or soldier on, finish as planned, and deal with the lumpyness when insulating. FWIW, insulation plan is 1/2" polyiso between ~4.5" sleepers, then 3/4" subfloor, then vinyl flooring.

You can, but I don't think the sealant you put in is subject to any wear, so you might not need the tape.
On the other hand, if you want to add the tape what you don't want is to spend the next 10 years wondering if you should have

Most of us believe the insulation will form over any irregularities in the floor. Lots of people have used pennies to cover the holes and they aren't very flat either.

It's the wood between the insulation that I'm worried about, I was planning on 4.5" strips of plywood with 24" of insulation between, which means 4 boards and 3 insulation pieces across the width. That puts lots of tape pieces under wood. Bonus air gap I suppose?

The tape thickness is insignificant...and probably a bit compressible...apply and forget[emoji41]

Water can get in and get trapped...and every hole invites bugs
