Under seal alternative / rust protection

[eddypeck]

I keep seeing this as a sponsored ad on Facebook and it's got me intrigued:

www.lanoguard.co.uk/collections/moto/products/lanoguard-vehicle-underbody-and-chassis-care-kit

Any thoughts or opinions?

My Mk2 Golf would alway benefit from all the help it can gets and an advisory on my Mk5 this year was surface corrosion on the rear subframe.

I've had previous advisories ('71 Beetle) that the car was heavily undersealed - therefore hindering inspection and potentially hiding issues.

No idea about that stuff

I generally think it’s a waste of time though

The traditional black under sealant just covers up any nastys and accelerates the process by trapping water

I would certainly agree with Karl on the old black under seal stuff. To be fair, it may be different if it’s applied to spotless brand new surfaces but I’ve applied it to old but prepared metal and been horrified by what I’ve found underneath it years later. I think it actually traps water and accelerates corrosion in many cases and because it’s flexible, it doesn’t flake off like paint and warn you of what’s going on underneath.

Good for hiding bad welds from theMOT tester but little else!

I too would agree "the old black underseal stuff" may well make the problem worse.

But with welded repairs - unless you can get to the inside and get this clean and dry - what else can you do?

I tend to still use Schutz stuff still. But this is still bitumen.


If you wanna hide some welding up for an MOT the time honoured method is:

That was kind of the point to my asking. As this seems like an alternative to coating the underside of the car in thick nasty bitumen.

FYI, I have both of the products available in my garage, you know, just in case ;-)



Although sort of answering my own questions here, found this: www.lrukforums.com/threads/lanoguard.263823/ these guys seem quite happy with it.

I might try some of this product myself - if it works here on Skye, it will work anywhere.....

I was having the conversation about lanolin-based heavy greases the other day with my mate; the old Castrol Heavy grease was made like this, I believe, but you cannot get it now for any price anywhere. The kit linked above includes a pot of the stuff, so I might just give it a try! Even if the grease is the only good stuff, it would be worth it; Castrol Heavy is the only grease that will keep tow-hitches working, and I really miss the way it allows Series_III door hinges to move for more than 6months in a lifetime.
