How bad is my boot? Be honest

If your car has ever been driven in the rain it is all but guaranteed that the highlighted area under the trunk is going to have surface rust. Nissan went super, super cheap on undercoating starting with the R33s and it got even worse in the R34s. You'll notice the undercoated area has no surface rust but the area that is merely painted with what looks like primer or base coat tends to show surface rust easily.

You can arrest the spread of rust in those areas by using a lanolin-based undercoat and it won't matter anymore, the oily grease will stop rust from progressing further. If you really want to go crazy you can do what I did and have the entire car taken apart by an R-chassis specialist so they know what NLA parts to treat like platinum and have the subframes/suspension components powder coated and the entire underside resprayed with urethane undercoat. At that point though we're talking about spending the value of the car itself in restoration.

thank you, all. I feel like I can’t just leave it as it is as I’ve already removed some of the sealer etc.

just to clarify, are the following steps correct and do I reinstate seam sealer at the very end, after I’ve repainted?

1. Rust deoxidiser

2. Septone

3. Primer

4. Paint

You won't need a rust deoxidiser with Septone converter.

I made some progress. Removed most of the tar and a bit more of sealer.

is there an easy way to remove the hose/plastic circled in yellow? I cannot get the wire brush in there as there isn’t much space. I’m trying to avoid having to buy a Dremel. Or is that the only way to get in there?

You're keen.

It looks like whatever that is has a rubber grommet at the bottom that comes inwards. Get behind the rubber lip with a broad bladed screwdriver and it should pop inwards

I took the rubber grommet of but the cable wouldn’t move. So Dremel will be the only way it seem. What did I get myself into

I’ve now got all the stuff I need to complete the project but I am struggling to work out where to stop?!?!?

Have I removed enough of the rust and seam sealer or do I need to keep going? Would appreciate any advice.

you have removed enough....let the chemicals nuke the rest.

And the paint shop supplier had no idea that boot floor paint wouldn’t match that of the exterior paint? Should have done more research I suppose and not relied on them.

 

doesn’t look too bad, does it?
