Underseal

[Benmac]

Some kind previous owner has undersealed the chassis on my Elan. Whilst this is good in structural respects its not so good in aesthetic terms as in a few areas its a right globby mess and is all over bits that don't need to be covered (brake lines, bits of bodywork).

I attacked the rear end of the chassis with white spirit and elbow grease at the weekend and cleaned it all off. There are areas underneath which are a little rusty where paint has gone but nothing to worry about. Now I am going to recover it with something rather than just leave it bare but what do you guys reckon is best?

Good old gloopy underseal maybe applied more judiciously or the clear Waxoyl? I quite fancy the latter so the chassis itself is still visible IYSWIM but just wondering if this is suitable.

I have used the clear Waxoyl on the suspension and the rear chassis for similar reasons. IMHO it is quite soft and may wash off over time (though I have no evidence of this). IIRC Dinitrol was used originally and looks to dry more like a thick wax therefore maybe a better, longer lasting solution on exposed surfaces. Also try searching for POR 15?

When I rebuilt the rear end I repainted the rear chassis and clear waxoyld it. As you say, it is soft and washed off/disappeared much faster than dinitrol wax which dries into a hard coating.

The summary of the story is that 5 years on, the rear needs stripping and repainting again, whereas the middle of the chassis which I treated with dinitrol still has the hard wax coating.

It is a shame, but I think for a British owner with our roads and weather, we cannot afford the luxury of aesthetically pleasing undersides!

Good stuff, I'll repaint the bits of the chassis where the paint has come away and once that has dried I'll put some proper underseal on it just a bit more neatly than was done previously.

It only seems to be a problem on the 'fiddly' bits of the chassis. For example the main spine of the chassis is covered neatly in nice even underseal with no sign of any problems so I'll leave that well alone apart from just cleaning it. The little attachments on it though where the seats bolt on are not as good where the underseal has flaked off so I'll redo those.

Ive got my car booked into this place next wednesday. http://www.rustmaster.co.uk/index_32017.htm

Quoted £300 all in and guarantee no overspray where you dont want it. They also said they stop and advise customers of any repair work required once preped ready for wax oil.

anyone on the forum used this garage of have an opinion I need to know before I fully commit.

Nobby, do they give a guarantee of how long it should last ?, if it needs doing every year then its expensive, but every 3 years seems a worthwhile investment if it lasts that long.

Hi Paul,

over the phone I was told up to 5 years which made me thing this was worth it. I liked the idea that they also use different nozzles and fitments to get into all the difficult places which would be missed or left if I did the job with the car on axle stands.

Well the deed has been completed so the chassis should be protected for upto 5 years.

As promised very little overspray! Quite a tidy job considering the nature of the task

If anyone else is interested, mention my name and you can get a 12% discount on £299.

If a group booking of 20 is made and they dont have to be all wax oiled on the same day, just booked with a deposit (he can only manage a couple of cars a day), he is willing to offer 20% discount.

This guy is based on a farm and is small time, but does have contracts with councils and plenty of Land Rover custom.

hi,
have done the same on my 95 s2..and would recomend por 15 paint on the chassis..goes off hard..have painted all the front suspension, wishbones and makes a nice smooth finish with no need for waxoil on the outside of the chassis,as dirt etc sticks to it.. but have injected waxoil through the small holes into the inside of the chassis, wishbones etc..looks nice and clean now...one word of advice, if you use por 15 DONT GET ON HANDS AND WEAR GLOVES as has taken 1 week to wear off, cellulose thinners, paint stripper and any other cleaning stuff i could find couldnt shift it...have fun
