Anyone used underseal on their outriggers?

[TheGriffalo]

As per the title really. Anyone used that rubberised underbody sealant on their outriggers? I'm considering putting some on the top of my outriggers as an additional barrier.

Currently going for two coats of zinc primer, two or three coats of Smoothrite with waxoyl where you can't get to. Am I being paranoid?

Just wondering if the underseal will help or become a water trap.

Denso tape would be better.

I tried 'Hammerite Underbody Seal' in an attempted corner cutting measure and it looked pretty cack tbh. I cleaned it off a few weeks later and did the job properly using Epoxy Mastic paint which is very tough in itself.

In your case I would be worried about the smoothrite chipping, so you may need something.

Yes. The sections in the wheel arches and along the sills, I painted them with POR15, undersealed over that and sprayed Waxoyl in wherever I could.

Can you remember which product you used? How has it held up over time?

True but I doubt it'll fit between the body and tubes

Exactly what I did. I don't care what it looks like, I care that the steelwork is protected.

Griffalo, I have just done mine today with hammerite underseal.

Look under rustproofing>underbody seal.

Mikes AJP griff has been done with this too.

Availaable from Halfwaits ,£4.95 for a litre tin.

Hamerite primer, Smoothrite and then Dinitrol.

Hammerite Vs Dinitrol... Discuss

I use Dinitrol 4941 Underbody Wax over Smoothrite on the outriggers to protect from stone chips. Been using for years on high impact areas.

The Waxoyl one. And so far as I can see, fine. The sections in the wheel arches have never shown any signs of corrosion.

Is this like epoxy pitch? This is what I used and I found it worked nicely.

I dont know

It takes a few weeks to fully cure, but is very tough yet flexible. Beauty is it goes over clean metal, rust, powder coat no problems.

Is there not the possibility of sealing in moisture by using underseal. ISTR this was a problem back in the 70s when cars were undersealed at the dealer having been transported along gritty, dirty roads to get there.

I presume that's why one normally puts the highly penetrative, water dispersant Waxoyly stuff on before getting busy with the undersealant?
