I would clean the outside / underside really well before sticking the sound deadening, and then apply some polyurethane sealant from the outside over the hole and the exposed sound deadening. That gives extra protection against water ingress (but will not allow water to drain

There are several options here, depending, to a certain extent, on the type of hole.
For a plain hole, the simplest option is to put a nut and bolt through it. If you choose a relatively low profile bolt such as a button head and then cut a small hole around it in your sound insulation, it will disappear within its thickness. I did something similar when fitting Gywn Lewis rear mud flaps, incorporating nylon washers as isolation for the stainless bolts, and when carpeted you can't tell that they're there:  Click image to enlarge This approach also works for threaded holes, which is what I suspect you have having removed your rear seats. An alternative for plain holes that you definitely won't need again is to stick some small pieces of aluminium to the underside of the wheel boxes with Sikaflex or similar. This maintains the flat surface internally and is nice and easy to do. I used this approach on my old 90 that had had lots of holes drilled by a previous owner: Click image to enlarge This won't work where you've removed seats from a Puma as there are braces underneath that would get in the way. They contain the threaded holes mentioned above, though. Darren 110 USW BUILD THREAD - EXPEDITION TRAILER - 200tdi 90 BUILD THREAD - SANKEY TRAILER - IG@landroveranorak "You came in that thing?

I have also taken out the third row of food down seats. I used these

I would stay away from fitting bolts for the sake of plugging holes. Why introduce a potential source of galvanic corrosion when there are alternative ways to plug. In the automotive industry, holes are usually plugged with grommets. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing

I used plastic bolts for the threaded seat base holes.

I'd just have them welded up if your not going to use them again

I just used plastic plugs, from the inside out, and a spray of dinitrol easy enough to get out again in the future, I also punched a hole in the dynamat before fitment allowing for future seat refitment. DEFENDER 90 TDCI XS,

Thanks all for your input, very useful.
Think I am going to go the plastic grommet approach, does someone have a link to suitable ones to use please? Thank you. |

from memory I think they were just the 10mm ones left over from a dinitrol kit but there are loads of options on Amazon or Ebay
link to the dinitrol ones below but please check the hole sizes before ordering anything https://www.dinitroldirect.com/product/din...-50-plugs/ DEFENDER 90 TDCI XS, I hope everyone is well and your land rovers make you happy |

You can get some of these - basically as used in production.

Given the hostile environment that is under the rear wheel arches, I'd want something more substantial than that. Also, if you are removing seats but leaving the brackets underneath, you really want to protect the captive threads in case you want to use them again. Darren
