The TR7 that I’ve just bought has been treated with lanoguard. It’s been on the car about a year and is still working well. Where it’s been applied thinly it’s dried to a semi gloss Sheen and isn’t tacky at all. Where’s it’s been applied more thickly it’s remained soft rather like lard, you can scrape it along with a finger. In both cases it’s remained excellent at repelling water.
It’s still working on the Traveller, although I don’t see the owner so much now he was commenting on how good it was when we last saw him back in September.
By contrast, a fellow Minor owner didn’t like it. He applied it very thickly and was disappointed with the way road dirt stuck. But then by his own admission he did apply it VERY thickly.
