Paid £400 only 18 months ago to have the entire underside of my GTR undersealed.

Had it up on a lift yesterday. Half the underseal has disappeared.:chairshot
Not impressed!! How long is this stuff supposed to last? Going by the bit where it's fallen off, it's not a recent thing either.

So need to spend a bit of cash on getting the underside pretty and to find another place to do it again.

Anybody suggest a good place to spend about £2K getting the underside of the car pretty again?

What I want is all the brackets etc. removed, galvanised, and the entire floor cleaned and resealed. Stainless bolts (and I've got a stainless kit for the diffuser on the rear). I want to completely renew it.

Luckily no serious rust, but the bit that hasn't been covered has started to suffer, so it does need doing. I don't even drive the damn thing in the winter, so annoying!

the only way is to strip and paint. why do you think manufacturers dont paint the top side in underseal. a, its the wrong colour lol and b, it comes off. i painted mine in 2003 and have just tidied it up .still looke very good. done this with all my cars..

So how about that POR15 stuff?
As far as I remember after hardening it's like an epoxy shell, possible to chip it but should stay in place

Toni, unfortunately this sounds like a very familiar story!!! :(

You have the right idea, the 34 has so many brackets, hangers, support bars, etc. etc. to do it properly everything really needs to be striped of and then all the old crapy tar like under-seal, that will have been half heartedly slapped on for £400 quid, removed, the metal then needs to be treated, and then base coated, and top coated! And the only product to use is POR15, anything less is a waste of time!! Some of the Dintrol products are useful for spraying inside the box sections, and perhaps to cover the high impact areas, wheel arches, etc. But POR 15 first!

I know you hate FB (me too actually!) but if you would like a recommendation PM or email me and ill send you a link you can view as a guest!

Steveline, do send me a guest view I'm sure it'll be interesting.

Don't think I will take it back, I don't want the same guys on the car again if they can't do the job properly the first time.

I've had a few PMs and recommendations, will take time to think about what to do.

Hey Toni just got back from a week in lovely Turkey and my attention was drawn to this. Drop me a pm if you want me to have a look at your 34 for you?
Cheers

OK guys, after much thought I decided to give the car to Rogue Motorsport in Coventry, ordinarily they work on all my MR2s but I have a lot of faith in them as an outfit and they were very keen to do a GTR.

I'll update as appropriate, but suffice to say things are looking like they need a hell of a lot of work under there.:runaway: Currently we are deciding wether to remove the subframes and suspension and do the job properly!!! God it's a nightmare and I've had to keep hold of all play money as I'm not sure what it's going to cost yet.

I also need to replace some parts, I'll be putting up pictures in wanted to see if anyone has some good condition ones kicking around. Otherwise it'll be new Nissan.:bawling:

Almost certain I'll need to replace the exhaust too...it's on the point of giving up.

One other thing, you'll never believe this but some muppet in the past has drilled through my floor and fixed some pipework to the car with a normal bolt and now we've got to strip the inside of the car to get it out as it is just spinning. Arrgh!

I'll put up some photos shortly, but UK GTRs, be very afraid!! Even though my strut tops are clean there's a hell of a lot of attention needed underneath.

I am sure it won't be cheap, but as I say I know them! I can also see the car on a four poster and break out into a sweat in person, LOL.

I've just done mine, stripped back to metal Kurust just to make sure any surface rust remaining is treated, 2 coats of anti-rust primer, a coat of hammerite and then undersealed.

Should be good for yrs. :D
