Renovo RUP5001117 International Ultra Proofer, 500 ml, Neutral, 500ml

I cleaned our mini's roof for the first time in years with the cleaner from the same brand.And followed up with the waterproofer.For a while now the roof would become saturated with rain.But after one coat of this (using the whole bottle) the rain that same night sat on top of the roof in beads and puddles. I'm very pleased with how quick and easy it was to use.

Fab. Restored my MX5 to being waterproof again!

I've used this product on both a 2001 Vauxhall VX220 canvas roof, and a 2004 VW Beetle Convertible. I've not tried Autoglym's alternative - so can't compare this product - but I hear that it's a good product also.I applied this product to both vehicles following the application of Renovo's Canvas Cleaner (a product which I was less impressed with). Obviously, your external roof surface has got to be clean prior to using the Ultra Proofer, as it will part seal in whatever is showing on your roof, for a time at least.Tip: In addition to whichever cleaning solution you opt for, I found an adhesive roller, like the Caraselle Lint/Pet Hair Remover (£4.50ish) really useful at getting hairs and all sorts of other material off the roof surface. You'd be surprised what it difference this tool makes visually, particularly on roofs more than a few years old.A single 500ml bottle of Ultra Proofer will not go very far if you're clumsy with this liquid or apply it unevenly. Take your time when applying and DO follow the instructions particularly with regard applying the product in a single session if possible. If you have to apply the product over two sessions (as I did once) then try to complete a roof 'panel' at least, and paint the product as far a seam (or join) on the roof material, so that any disparity in the application won't show.The product works well, and both roofs now nicely repel and bead water on the surface. If you use a high-pressure washer, then avoid the roof surface altogether. Rinsing the roof with a high-pressure lance will simply take off any previous weather-proofing straight away.Hope this helps.

I have been using fabsil up to now but this is much better than the basic fabsil. Putting the 2nd coat on is interesting as the first waterproofs it so well that it is hard not to get the 2nd coat beading and running off! Take it slow and brush any runs asap.The finished roof looks great and should bead rain nicely and reduce mildew growth and staining of the fabric.Recommended.

As other reviews say, this is really effective. Seeing rainwater bead up and roll off is very satisfying!I've been using this stuff for years, and after some experimentation I find the easiest way to apply it is with a small sponge. The first coat is easy enough, but by the time you try to apply the second coat the roof is already pretty waterproof, so the new coat tends to bead and run off. Using a sponge causes the second coat to be absorbed with minimum faff.

Very happy with the quality and finish. I purchased 0.5 litre which was enough for a 6 series BMW roof - 1 coat with a little bit leftover. I put it on nice and thick, and after 2 coats of the black roof die. I needed 1ltr of the roof die for 2 coats.I used the cleaner first then the die followed by sealer. 3 stage kit. I followed the instructions and used a new 2” brush for each stage. The cleaner then die before the waterproof and sealer (last stage) which offered a great total job. 3 stages took a while including drying but very happy with the end result.

I love the majority of Renovo products - I recently used their cleaner, reviver and waterproofer products for my car's annual roof maintenance schedule.The cleaner is I think the only soft-top cleaner that contains anti-mildew and mould inhibitor, so can help stop green spots from appearing on your roof.The reviver transforms your faded soft-top to a nice deep black again.However the Ultra Proofer reviewed here doesn't really seem that effective - I gave it the required number of coats and rather than seeing the water bead off even after a prolonged downpour, my roof was saturated (not really a problem as it has an impermeable layer underneath, but it's nice to see it running off!)I followed this up with a couple of coats of Fabsil Gold, and now the water beads off perfectly even after it's rained all night - in fact it's a pain as when you open the door and get in all the droplets collect and you get wet. :)I'd recommend you try this and if it works for you great, but bear in mind you might get better results from Fabsil Gold.
