Removing rear bench seats...plugging the holes
So I'm going to remove my rear bench seats to make a more practical load space, but this will obviously leave holes in the floor... So what's the best way to plug these? Silicone bathroom sealant?

Sealed Aluminium pop rivets if they are relatively small, if not then rubber blanking plugs is usually the solution.
Or you could use dome head hex cap bolts, but if SS beware they donโ€™t seize so corrosion block would be a must.

As I said depends on how large they are, situation, what is the other side of anything etc etc. $W33T $0U7H3RN $UG4R

Think they are about 10mm judging by the bolt heads. They are directly into the wheel arches so important to properly seal!

Will have a google and see what I can find. Thanks for heads up on SS. Will bear in mind.

I think how you address this will be dependant on what you want to achieve. Are you trying to make your floor look smooth and nice as though there are no holes in it, or do you want to blank the holes just to stop mud/water/noise?

If it's the first then I think you need to get some discs of just slightly smaller diameter and thickness and then stick them into the hole using a backing plate and use an adhesive sealant to put them on - though I am not sure how to clamp it whilst it cures.

Alternatively you could do the same thing but without the little filing discs if you are not worried about the asthetics.

The easiest way would be to just bolt in a fixing, but that will stick above the surface of the plate and if in the load space hinder sliding things in or out. But I suppose this won't matter if using a load liner.

I suppose a slightly off piste way of doing this would be to fit a flush fitting nursert, fit a grub screw to just below the surface, fill it and sand it - a bit unconventional but it may work for you. I would seal the grub screw in if you do it this way as you don't want water getting in the threads and rusting.

Good luck.

When I did the same in my old 90, I fixed some offcuts of aluminium to the underside with Sikaflex, which means that there was nothing projecting above the surface inside. It was then eventually soundproofed and carpeted so the remaining hole was hidden.

Just an add on to the comments above. It's not a good idea to use bathroom sealant anywhere on the the car.

As it cures it releases acetic acid. I don't imagine it's the worst acid out there, but better by far to use a PU sealant/adhesive. I think I read elsewhere, and on here that there were other reasons bathroom sealant wasn't a good plan - but I can't remember now!

PU sealants - tiger seal, upol etc will more commonly be available in black, but you can find white..... if that's what you want. Donald

The silicones in silicone based sealants make it basically impossible to paint the area afterwards, so it might well have been that!

I used large head rivets, penny washer underneath and a blob of PU sealer You will be surprised how many holes there are once you get the seats out.

An epoxy resin works well for patching. I patched various holes on my first Series 1 80" in 1978 which are as good today as they were when patched.

if you just want to seal against water but leave the holes to maybe refit the seats then get some door trim clips. The "fir tree" type are available in many sizes and are almost flush and can be sealed with some DumDum. Plenty available on ebay.

Epoxy is pretty damn good to which Blackwolf mentioned. Iโ€™ve never used it for that kind of job but when I have itโ€™s always been a success when I have used it on other projects. $W33T $0U7H3RN $UG4R

Thanks All. Weather is stopping me doing much at teh moment, but I've got some rubber grommets arriving that I'll use for now with some dumdum, and think about something a bit more permanent once I've fitted out the inside (which I might be able to re-use the bolt holes)
