How long does the 'as new' waterproof last?

On the bottle there is reference to the product being used every 6 months for the ultimate proofing

I have an Audi A3 soft top, the roof looks very clean(no green mould or marks) do I need to use the roof cleaner before reproofing it? also will one bottle of Ultra proofer be enough or should i need two

As you apply the proofed you might find there's more dirt than you think! But if you're sure it's clean, proofed alone is fine. I only ever used the cleaner once, first time I proffed the top. I use a 3 inch absolutely clean paintbrush and work the proofed well in when there's no rain about. Fantastic afterwards to see how the rain beads on the surface and runs off. A small bottle goes a long way.

Should the renovo ultra proofer smell like rotten eggs ?

Mine didn’t doesn’t sound right to smell of rotten eggs (hydrogen sulphide) I wouldn’t go sniffing it any more. Out of interest how old is the product you have and was it stored at an adverse temperature ?

Is the item easy to use

Hi Warren,i found this product very easy to use. If you get a good quality 2" brush and follow the instructionsyou'll have no trouble. The product is almost water like but a thicker consistency and i applied it like i was painting, up and down ,side to side and then up and down again. My car being garaged, i was able to leave it to dry for a fewdays and then gave it a second coat. This stuff made the top like new again as i only realised this when i went to fold it down.The material was thicker than before i started so i had to help the folds as it folded down into the boot.My car is a 1997 saab 900s Since i used all three products in succession i covered the car completely in plastic drop sheets.Raise the roof up first,cover your car totally with the sheets then close the roof again, savesa lot of cleaning later.Hope this helps, Kenny
