Undersealing

Can anyone give me tips and advice on under sealing my 80. It's starting to show signs of light rust underneath and I'd like to arrest it now while its not too bad and before the winter.
What I really need to know is how to get into the little nooks and crannies to remove the rust and dirt before sealing. Is it worth paying for it to be done?
thanks in advance

Hi Mark,
It is a bit of a slow and messy job.
Ideally you need to raise the car as high as possible and get
underneath to clean it and then apply the protection.
You can use a pressure washer, however this can blow water past seals
and also you end up with a lot more over yourself. I prefer to get a
garden sprinkler and set it running under the car, moving it every so
often. The gentle spray will get most of the mud off the bottom,
although it does help to poke around with a screwdriver to remove the
big solid lumps first.
Once done, you need to cover the exhaust to stop it from getting
sprayed and then also remove the bumper corners so that you can get
into the chassis rails.
I use a 'Parafin sprayer' on my air line to spray Waxoyl on all
surfaces - you can get a kit from Waxoyl that makes it easier to get
into the chassis rails, etc, however the ley thing is that you probably
need some sort of air compressor.
Once done it should protect the car for some time, although best to re-
apply every couple of years.
Waxoyl is one of the most common products on the market, although
there are others. One of the key things with Waxoyl is to make sure
that it is warm/hot when applied - I keep the can in a bucket of hot
water for around an hour before apply (you will need to change the
water a few times to keep it hot) and I keep it in the hot water bucket
whilst doing the spraying.
At the end of the day it is a bit of a tedious job and you may findd a
local firm that specialises in doing it that will only charge a couple
of hundred pounds.

There are various systems available if you decide to do it yourself. Take a
look at www.frost.co.uk online catalogue/rust. If LC already u/sealed they
have systems to get into all the nooks and crannies. If its not u/sealed
it's well worth considering POR15 - which is brilliant stuff but do follow
the instructions.
