Hammerite underbody seal - yay or nay?

[benico]

Have seen it in Halfords - does it work, are there any cheaper alternatives (£12.99 for 2l), how much will I need, will to much salt on the road give my van a heart attack?

the stuff with added wazoyl seems v.much better , imho

I have always found that Hammerite (on its own) chips easily when applied to areas that get a lot of water and stone chips thrown at them. Paint and underbody sealant is my choice.

I agree, once chipped, rhe water will spread behind.

Clear wax oil is my choice, you can see whats going on behind it then.

Yes this is quite true on clean metal however I find that on pre-rusted metal Hamerite (not smoothright with seems to be an entirely different composition) will soak in and stick like the proverbial without forming a seperate layer effect such as found in plastic coating, which will peel back under the effect of creeping rust. I speak as a lifetime reclaimer of pre-owned vehicles due to an accident at birth (Poor parents).

Use my van every day come rain or shine and never had any issues with Hammerite, I use the spray lance for the tricky bits then cover every thing with the brush on stuff.
