I find the underside is not so well protected and I would like to have my car treated before winter so that it will last at least the whole of winter. I don't to buy some Tectyl at halfrauds and just climb under it and spray it around. Does anyone know companies who do this sort of thing properly? Thanks, Peter

 

Most garages with a lift and an underbody skutch gun will do this for you. I got mine done two years ago and used Waxoyl, brilliant stuff but a real mess if ur working at the car again, it always stays a bit sticky and gets on your arms hands etc when you are working around the car.

Great stuff though and ive used it on all my cars and it has kept them good and fresh in below!!

Two 5 litre tins of Waxoyl should be plenty do do an impreza.
