Underseal Application

Best not to use a 'hard' type underseal, as although they must have improved over the years they invariably dry out and crack. This usually leads to
the damp getting in and worse corrosion than if nothing had been applied in the first place! We have used in the past, with good results a product
called Dinitrol (number 3125), you could also try Waxoyl. If you had to ask me what protects cars the best over 30+ years, then it would have to be old
engine oil regularly applied. No one from the Green party would ever do it, but then it causes less pollution than manufacturing a new car!

Isn't this why Triumph carefully enginered the rocker cover seating on the SC engine, so that a regular supply of underseal would be applied from the rear left corner...? Leak, be damned, it's a feature I tell you!-

My "modern" citroen has this feature too
However I used "Hammerite" brand underseal on my spit. Supposed to stay soft and has waxoil in it. Having said that, I haven't checked it this year to see if it has actually dried out yet.

I applied the same 'Hammerite' Underseal to my spitty about 6 years ago and it's still nice and soft, and slightly tacky to the touch, so seems to be lasting pretty well. I've also heard that mixing in some waxoyl is supposed to help, but i've never actually tried this!

My can of underseal actually says "contains waxoil" on it. Waxoil and Hammerite are made by the same company.
Thinking about it, I think I overpainted my underseal with black hammerite to stop dust and crud sticking to the "stays tacky" underseal. Seems to work and means I can wash the insides of the wheelarches without getting black sticky stuff all over the sponge. Not sure whether it helps with the original purpose of the underseal or not though.

My Dad always swears by old oil and service includes spraying the usderside his old Volvo with dirty oil then letting it drip... humm...
I repainted the underside of my 1500 about 10 months ago with 'underground' paint from my local farming supplier. Other than being about 1/10 of the price of Waxoil, it is flexible and can be thinned down with petrol to get in all cracks. It dries in about 48 hours but even now is still 'soft' to touch. Great stuff,

My Dad, who gave me my first two cars, a workshop manual, a set of spanners and the instruction "If you want a car, build one!" used to do this with his Morris Minors - drain oil and fill chassis box sections with it. The car he gave me was black and filthy underneath but never needed any welding.
At the time my "workshop" was a great corrugated iron garage with earth floor. Once I'd filled the chassis with oil I parked the car in there and the draining oil water-proofed the floor for me. Now that's recycling for you! Funny how we never had a problem with weeds growing around the garage - or within a 15 feet radius of it - great smell too!
