Getting the roof prepared for some renovo treatment tomorrow . Roof was down all day today so im going to let it stretch out overnight and then add the black dye followed by the ultraproofer . Roof got a good clean on Sat past so is good to go for the black stuff .

use a sponge or a paint brush to apply, but bare in mind it goes absolutely everywhere as it's incredibly thin and runny.

looks good when finished though, so well worth doing.

good luck :thumbsup:
 
Yep, sponge or cloth for application. Use a paintbrush and you will regret it unless you mask the entire car!
 
Couldnt resist getting a first coat on . Wish i read ph001 post before starting :D
Man that stuff is runny city , panic set in as it seeped below the masking tape . Quick lesson learned and i removed the masking tape from the other half of the car and sprayed the quarter panels with a light spray of wd40 type stuff , any runs where quick and easy to get of the paint . I did trap a layer of bin bags in at the front of the roof and that has prevented any runs onto the windscreen . Looking good and shall get the 2nd coat on in the morning . Certainly getting rid of them white marks you get at the folding bits . Quick lesson for me , dont use any masking tape unless its water proof . Its fine though no drama

Personally, I wouldn't "proof" the outer hood layer. It isn't meant to be waterproof, and anything that stiffens the fabric even slightly can cause it to fold incorrectly.

Thats certainly something ive never thought about Mike . Its certainly food for thought , i know bmw sell there own roof proofing stuff which can be bought on amazon so i have to ask myself why if its not required .
https://www.amazon.co.uk/BMW-Genuine-Water-Repellent-Impregnating-Agent/dp/B00A4CAN0Q .
My concerns would be that after a deproofing roof clean in preparation for the dye then surely i would leaving the roof vulnerable to mould on the headliner if the car was to get wet and parked up in a garage . This could be a lively debate , should i or shouldnt i . Normally i would dismiss the thought of not proofing a roof as ive always done it with fabric roofs on classics ive owned . However im stumped now as i do respect the fact that youre somewhat of a roof expert when it comes to the z .
Hhmmm decisions decisions
Lets open up the debate on this one , What do think folks
"to proof or not to proof , that is the question "
:D
 
I certainly don’t think you will do any harm by proofing it. I think any stiffening of the fabric will be minimal. Proofing does give the advantage that it prevents any kind of mould growth.

The Z4's soft top has 3 layers. The middle layer is waterproof, so you cannot get mould headlining.

I've proofed my roof before and it still feels pretty soft. But the material is only a couple of years old, as I got a new roof fabric fitted.

The dye seems to be the product that makes the material stiffer, rather than the proofer.

The suggested cleaning method is to fully remove all dirt and stains with a soft top cleaning product then apply a diluted impregnating agent with a sponge. Remove excess water/agent with a sponge (stops spotting) and allow to dry, ideally in the sun. 8)

Because dealers would sell you a chocolate tea cup if they thought you would by it!

I am interested to hear how it works out, particularly with regards to Mikes comments.
 
Ok first coat has dried and heres my findings . Theres no question about it , theres a stifness has come into the pile . It dried evenly and the 2nd coat was so much easier to apply . There was virtually no runs at all , its almost as if the 1st coat give the dye something to grip to . Will see how it dries and jury is still out at this stage on the proofing . Going to watch how the water beads when the second coat dries . dye5.png
 
Renovo doesn't really bead well or for long tbh

i stopped using the ultraproofer and switched to gtechniq smart fabric and it's much much better (and way less hassle to put on tbh)
 
I read somewhere the proofer helps stops the dye fading over time.
I find the proofer doesn’t really make the rain bead. Unless it’s a light shower.
 
Not all proofers bead and that's not a bad thing they will all do the Terminator 2 impression when a cup of water is poured onto the roof but once it rains they just let the water soak through as they should.
 
Ok wee follow up now that im finished . Done the dye and whilst the colour was great i wasnt keen on the way the pile stiffened up . I ran with the ultra proofer and got two coats out of the .5 litre container . Defo conditioned the pile and im glad i went with it as the roof feels like its back to normal except its black . Very pleased with the end result . In summary .5 litre of the dye got me 2 coats as did the ultra proofer , if i was to do it again i would defo go with the ultra proofer as it conditions as well as proofing . Only downside i see is that it looks that good i dont want to put the roof down :D :D

I did mine with Renovo, this time last year and included the proffer. After 2 applications and a drying period. I had problems with the roof latching when opened and for the first 10 or so operations, was having to get out to push the roof down the last centimetre or so due to it being stiffer. Would not use the final coat in the future.
 
Looks really good :thumbsup:

When I did mine, I never used the proofer. In fact, I'm sure I still have a full bottle of it in my shed!

Interesting to hear that the proofer softens the fabric after applying the reviver. That's probably what I should've done after dyeing mine, instead of shelling out for new fabric :headbang: :lol:
