Underseal

I have just had my E50 treated by Devon undersealing. It failed the last MOT on some rust, had it repaired and decided to get it treated. Dan at Devon undersealing was brilliant. Inspected the van prior to quote and explained the process fully. He had the van for a week. I picked it up on Friday and highly recommend him. His work is exceptional.
 
The Elgrand was made for Japanese roads only. Due to their climate, they don't need to salt the roads and therefore they don't need to worry about underseal.

In the UK, however, this is NOT the case. Salt will eat away at the chassis and destroy your pride and joy from the inside out.

When you get a fresh import, buy from a dealer or buy privately... you MUST ensure the underseal has been done.

If buying privately, I would get it re-done no matter what the seller says, as it's sold as seen. But if you buy from a garage you will be protected by some sort of trading standards.

Underseal is basically a product that is applied to the underside of the vehicle that prevents the metal from rusting when it comes into contact with the salt and moisture on our roads. It is VITAL for a long and problem free life for you Elgrand.

There are many options available, starting at around £80 for an "in & out" service. Personally, I wouldn't touch these with a barge pole.

The best options seem to be around the £400 mark. This includes dropping your vehicle off with a garage for 3-4 days. One the first day, they thoroughly steam clean the underside of your vehicle. Second day they apply the first layer of the treatment and leave it to set over night. Day 3 they apply another coat and leave to set overnight. Then you collect on Day 4.

Also, please note that underseal is only temporary. It is not a lifelong product (unless you pay extra for a product that has a life long guarantee!). The quick £80 jobs should probably be done twice a year, at the very least, once a year.

The more expensive jobs should be topped up every 4-5 years. Speak to the professional who does your treatment for their advice as these time scales will vary depending on the product you are using.

I know a few people who are JDM car freaks who pay the £400 for a proper treatment, then £80 for an in and out treatment, and then go back and get the proper treatment re-done every other year. One thing for sure is that they will crash their cars before they rust!
Thanks.

They are using Waxoyl
 
I used rust buster in Spalding a few weeks ago, they use a lanolin based product, from what I researched it sounded good. Time will tell.

Hi Karl
Who would you recommend for 4 day underseal treatment in North East ?
Thank you
 
Can anyone recommend anywhere near Cardiff, South Wales?

I wouldn't say recommend as I've never used them, or ever been to Cheltenham, but these have a few positive posts on the MX-5 forum: https://www.pcmworkshop.com/rust-proofing/

Also, again never used them, but I googled these recently, Cowbridge: http://rustproofing.wales/

Again, I haven't got a clue about them, but just two 'nearby' places

Did you get your Elgrand from Colin Price and was it a fresh import? I ask that as he underseals them (Waxoil) when he gets them, and if yours is just a C. Price previously fresh import, just a few years on, maybe C. Price can top up your waxoil?

Thank you. I'm not sure where it was from. We bought it from a private seller and they had it for 2 years and they had also bought it privately.
This may be completely obvious, is there any way to see if it's been under sealed?

If you go back to post 90 of this thread it's all there.

I'd look at google images of undersealed cars (which, granted, will probably be photos of it just being done) and compare to a look under yours. Waxoil though (one many of the different products places can use) is more 'clear'.
Also, when you look underneath, have a look if it looks rusty. Not so much the exhaust box, but in general. This is as good an indication as any as to whether it needs doing- prior under seal or not.
