Lizard skin for my 66 SS or??

[Thumpin'66]

Hey guys, I have been researching a lot and can't decide on what to coat my floor pan with. I need to undercoat the pan since my ,etal work is almost done. I am considering Lizard Skin Ceramic. I can't get a straight answer from anyone on how many gallons I will need to buy to do my floors top and bottom. I am open to ideas as for as alternative coatings and am looking for personal experience feedback more than random product names. I only have a few days to decide so help!

I bought a 5 gallon bucket of each of the Noise coating and the Ceramic heat formula. I did the entire underside of my car and hardly used 1/3 of each bucket. Planning on doing my floors with the left overs.

I think a single 5 gallon bucket should be more than enough for the floors unless you are planning on laying it on really thick.

Summit had a good deal since their shipping on both buckets was only $11.

Here is some pics to get an idea of the coverage -
