Tetorsyl Ive always used. Never had any issues with it & its a lot cheaper then overpriced alternatives.

Any decent motorfactors in 5L tins for about £9. Brush on only tho.

Personally I'd avoid the brush on goopy underseal, it just such a mess to deal with should you need to work on any area of the car covered in it. Spray on stone chip is better in my opinion. The yellow cans of Waxoyl is good for spraying into the cavity/ box sections of the car though.

Tetrosyl isnt gloopy.
