I was after opinions on the best coating for the underneath of my old Volvo daily driver?

Old daily driver..........Schultz.

Schutz on my car too. Too early to comment though.

Dinitrol 4941/Car for the cavities.

Billet Hammer Hydrate 80 for rust inhibitor and POR 15 to paint over the top of the Hydrate 80

 

Check out Practical Classic website they have reviews on the leading brands, with annual updates on how each of the tested products are performing in the real world. They have sill cross sections with each product applied to them and as I say they report on how the product is doing, year on year.

Thanks for the replies. I've already got some hydrate 80, I used it on my last volvo. I like the bilt hamber products, I've used the dynax s50 cavity wax on my zed before.

I'll probably give the POR 15 a go.

I don't suppose anyone knows how much POR15 I would need for a fairly large car?

 

Ignore that, I've just found that 1 pint does approximately 50 square feet.

Im going to be using these for my zed :)

I used the hydrate 80 today and I'm waiting for the por 15 to be delivered. It states that it breaks down when exposed to uv light. I wondered if I'd get away without using a top coat being as it's under the car? Has anyone got experience of this?
