So I came to my coupe today with the intention of sanding down all the floor ready for paining tomorrow, however I've been met with something, and I don't know what it is, some of it was peeling off and it seems to be some hardened sealant stuff that's over all 4 quarters of the floor, is this original? Should I remove it all and continue with my plan? I'm going to assume it's probably sealant as the previous owner has just covered up the patches he did in the floor with sealant instead of paint

I can't add pics on my phone so sorry for no visuals on what I'm trying to describe

Sound proofing panels which would be colour coded on the surface and hard black tar underneath.

I used a hammer and chisel to remove it from above the drain holes. I then used a wire brush drill bit to remove any corrosion and then painted with POR15 paint.

Ah yep thanks guys.

I'll get it all off wire brush and paint over.

The areas I got off all looked alright underneath except the areas around where a patch had been put on.

If you're intending to strip it all off you might consider replacing it with something similar as sound-proofing, after you've attended to metal restoration...it's fitted for a reason

What's originally fitted does crack and loosen after time.

If you want to remove it, cool it down with dry ice (solid CO2), it makes it brittle and shatters if you put a scraper between it and the steel bodywork.

My x1/9 has the same stuff.

Hey Pete, come to think about it I watched a video the other month and the person did exactly what you just said, the stuff on my car is pretty much just peeling off by hand in some areas.

That wasn't by any chance that ace Swiss YouTuber MyMechanics, restoring his Datsun 240Z?

Not wasn't, it was some dude in America with a BMW stripping it out for drifting/racing

A quick question regarding the floor, I've got the drivers rear foot well all sanded down ready for paint, should I paint that now then do the same for all the other foot wells or should I leave it, and tomorrow wire brush the other foot wells and paint all at once?

Paint all at one go, saves time, potential contamination of fresh-painted surface and no messing around with dirty brushes

Yep thought so, began working on removing the sound deadening stuff from the passenger side

I'd give it coat of primer to make sure any exposed metal/treated areas don't flash rust on you. Nice thing about primer is that it's really easy to flat any imperfections and blend it.

Just watched this, wow that is some attention to detail on that Datsun, a very interesting video to watch

It's off-topic a bit but for sheer class it's worth watching his other stuff. Take a look at the amount of subscribers....
