Rated 4 out of 5 by from Good product Been using this underseal and waxoyl for many years. In various delivery methods. Spray can, as a brush on, and from a spray gun. Both at home and in a car bodyshop. Best applied as a preventative before any corrosion. But can be applied over treated corrosion. Of course its always best to remove any and all corrosion and prep the surface accordingly. The 600ml spray cans do cover well but multiple cans are normally required if doing an underfloor on the average size car. Product does dry fairly well from its initial state, although it will remain waxy, needs at least 6 hours before vehicle is used. Preferably 24 hours. Don't use on anything that gets hot, even fairly warm areas can melt the underseal. Also bare in mind that using this on say suspension parts while OK and will give protection, upon working on the part it will be messy. Product does not dry completely like a stone chip would.

Can this be used underneath a parked car ?

I’m just wondering how well such a tall can would work in a restricted space ? Will it still spray if the can is horizontal or even at 45 degrees ? Would it be better to use the brush on product if space is restricted ?

Do you have to treat existing rust before you should use this?

Asked by: QforU
Yes, it’ll hold back rust from getting much worse but I’d either grind it back or apply a decent rust converter

Can you overpaint this product

Asked by: Genty1960
As this product needs to be flexible it remains quite tacky so we would not recommend overcoating it.
