Hi guys.

I just been to the pub with me old man and we got talking about maintenance items that he used to do as a young man that are not done anymore.

He mentioned that he took his car once (a Hillman Avenger he tells me) to his mate who painted a thick tar-like substance on to the underside of his car to protect it. He couldn't remember the name of this stuff.... anyone any idea out of interest what they would have used back in the day?

Afraid underseal is as far back as I go in this regard.Although it was laid on really thickly in places-mainly to hide some type of bodge repair!!

[Varche]

Good question. I remember it was very popular in the 70's. I bought a Morris 803 (1000) that had a very very dodgy chassis repair hidden by the stuff.

I remember helping my dad gunk up his Capri with the stuff and we also fitted an Eflow(?) sound deadening kit. Thick wads of what can best be described as carpet undelay. Glued to under bonnet, under the seats etc.

vx/opel use a yellow , thick substance instead of tar..

but still I'll prefer epoxy

[pscocoa]

Ziebart was the brand that comes to mind

You can still buy that thick tar stuff , brush on or spray on . Engine oil is good also

he said epoxy is ringing bells .....

That's the only brand that I remember.

Think I used some in the 70's called Tetroseal.. used it on sills to cover fibreglass repairs !!

Early 70's ....  Fiat 850 Sports, so full of rot that on doing an emergency stop my heel went through the floor pan .. ... into garage, made a thick papier mache mix and some cardboard, and filled in all the holes, then acquired a couple of catering size beans cans from the mess, which we flattened and attached either side of the cardboard with more papier mache .. allowed to harden for a week then covered inside and out with a thick layer of underseal ... the tin cans were there in case a magnet was used to check the floorpan .... then drove to a mates farm and spent 30 minutes doing doughnuts in the milking yard slurry .... quick rinse of the body but NOT the underside (boy did it stink), left for another week, then drove to a garage and traded it in ..

Black underseal had many uses .......

Waxoyl is another still widely available too...

[symes]

bet it was bitumen tar-that wouldn't surprise me at all

Yep. that was the brand at the time, and as a then Junior car salesman I used to get Commision for selling it, or giving it free to clinch a deal........My other life, those were the days.........

Used to use auto schutz underseal back in the 60s - think its still available.   Waxoyl was good for injecting into chassis members as it had the ability to creep into joints/corners

Oh yeah, I'd forgotten about that brand. Schultz underseal was very popular for the diy'er back then.
