Picked my new 86 up yesterday. While having a general look around it I noticed that there is a large amount of underseal type protection on the inside of the front wheel arches. After a drive today I noticed this coating had become hot and sticky, almost wet, and when touched, came away leaving a large amount of it on my skin. It has already accumulated a large amount of road dust/small stones that have embedded themselves in it after just 80 miles. Is this normal and has anyone else noticed it?

Can’t say I’ve poked my head in to the arches of mine to take a look yet. I’ll have to have a nose next time I take it out as there’s no way I’ll be able to contort myself into position while it’s in the garage.

Looks like some shitty waxoyl type product straight out of the 1970’s!!
 
Just had a look at mine and it's the same. Even in todays warm ambient temps the stuff is semi liquid, my hands were like yours 🤦‍♂️
 
Had a talk with the dealer and they said it is applied by Subaru for transportation and eventually it will come off! Only time will tell.
 
It's so wet, I reckon it might be applied in Derby during the PDI.
These need the protection, Toyotas aren't immune to rust.
I've sprayed some Bilt Hamber Dynax on the suspension arms also to protect them.
 
Hi all, just reading this thread.

What is the best way to protect the cars underbody ? Dynax UC ?

Also wondering what to do with the black ‘temporary’ coating that is mentioned above ?

Timely post, I had mine undersealed today by Krown Rustproofing nr Birmingham, it's a Canadian product. I'm told it will last 2 years daily use easily before a top up (up to 5 if just a weekend car), and appeared to be a thorough job.
The alternative is using things like Lanoguard as DIY but that will need redoing every 10-12 months apparently for the same level of protection

The chap pointed out the gloopy stuff in the wheel arch liner above and doesn't look like it'll do much, also isn't in the right places for where rust is likely.

Quite shiny this stuff :

Thanks @Beans !

Did you have the black stuff removed ?
Think it was just left on. That black stuff is just on the liner anyway so I don't think it's actually doing anything to prevent rust.

Those liners were removed taken off for the treatment and the chassis underneath was coated in the good stuff

The black underseal stuff sprayed under the arches has made its way onto my wheels and tyres, or was carelessly sprayed onto them. This is the inside of my NS front wheel which has felt out of balance since pickup. Now up to 350 miles and it seems to be peeling off the tyre wall. Might be something to look out for if anyone has their wheels off.

I think underseal would be applied in UK as they would not be applying it at the factory with the wheels on and arch liners in place..

Understood. Will have mine sprayed under the liners. Likely to have Dynax UC applied.
Dynax UC dries clear and doesn't seem as greasy as Lanoguard or the old Waxoyl.

If you are a bit handy, you could do it yourself with a couple of cans, they come with long straws.

Just do each corner in turn. I coated my wheels at the same time with Gyeon rim.

A bit of white spirit or tar and glue removed should get it off.
 
When my wife's car got completely covered in Bitumen from a poorly set road surface, I took to it with a few cans of that GT85 spray from Aldi (available elsewhere too) and some soft rags. The car came up lovely and clean.
Couldn't get in it though as it was like trying to catch a fish with bare hands, slippery as f***k .... I made that last bit up btw :p

Thanks @Beans This looks like a good option. Can I ask how long they had your car for and whats the approx cost?
 
I applied Lanoguard last week (forgot to get any pics) Only did the underside so far as I hired a ramp to make it easier (only took about 30 mins and no crawling around on the floor) Will get the wheels off in due course to do the rest of the suspension components from the wheel well side as I couldn't do it on the ramp as the jacking bar was fouling on the underside trays and exhaust.

Hi , seems good stuff bought a couple of a spray cans of Dynax UC from Opie oils last week 20% discount.
Only gave my car a light first coat on the suspension components I could not really reach any further.

They had it for about 2 and a half to 3 hours, was quoted 3 hours. They charged me about £270 which I thought was very reasonable actually, given its supposed to last a couple of years. Robert seemed very thorough and knowledgeable on the topic as you'd expect.

Also worth noting, they removed the rear lights which initially thought was odd, but like the gt86, there's a small gap where you can spray to get to the inside of the arches too!

Would recommend, but equally know that lots take the DIY option and I'm sure that works okay too
