Hi Folks,

I just bought a 2000 Z3 Roadster and am looking for some recommendations on how best to maintain the black canvas convertible top. What cleaner(s) is best to use? Do you use a rag or a brush? Also, does anyone use anything to waterproof the canvas? Something Scotch Guard-like comes to mind. The original top still looks like new, and I'd like to keep it as long as I can. Than you for any help!

OK, so why did you ask for our advice?
303 Aerospace Protectant is a good product, but for plastics. The top is fabric. I'm not sure the salesperson at the marine place understood that. I would not put that on my top if I were you.
The RaggTop product (plus a few other good products) does a good job on fabrics.
The Plexus is a good product for the back window, though.

... went to West Marine today and bought... 303 Aerospace Protectant to waterproof the top.
The 303 Aerospace bottle says "Vinyl-Rubber-Plastic-Leather-Fiberglass". The back label says the only fabric is it recommended for is vinyl -- and says "vinyl soft tops".
I suppose if it is OK for animal leather, then it should not harm another organic like cloth canvas. But evidently 303 Aerospace is not the best product for canvas convertible tops, or the manufacture would say so.

Whoa, hold up guys.

Blacklane, I followed your link to the tread that mentions both RaggTopp and 303 (posted by z4mconona).

Considering that I live in South Florida where the sun is harsh all year round, I went with 303 because it is recommended by the company Sunbrella. Sunbrella makes the canvas material that is used for boat covers, bimini tops, as well as patio furniture. I figured that if it's good enough for them, it's good enough for me. Turns out that 303 sells a few different protective products. One of which is "High Tech Fabric Guard" (http://www.303products.com/303r-fabric-guard-16oz.html) for use with "all fabrics, carpet, and upholstery".

So you guys did help me. You pointed me in the right direction with a few links that gave me some choices that ultimately resulted in me buying what I needed.

Thank you!

So did you get the fabric guard or the protectant? The fabric guard is what you want for the canvas, after it has been cleaned/dried. I used a cheaper alternative from Advance as I needed to get this done without having to wait. It is a good product. Available at Amazon as well.

You first said you bought 303 Aerospace Protectorant, which is not for woven fabric. Are you now saying you bought 303 High Tech Fabric Guard, a completely different product that is made for woven fabric?

Most all convertible tops are made from a Hartz Co. material, called CAMBRIA®, STAYFAST®, TWILLFAST®, or SONNENLAND®, which is "Solution Dyed Acrylic Topping Fabric". I see it is not organic, but is instead acrylic which is an artificial fiber, actually an extruded filament.
For cleaning and treatment, Hartz recommends this combo which is available from RoadsterSolutions.com:

Vinyl is a plastic sheet, on which you would use 303's "Aerospace Protectant".
Acrylic fabric is a woven cloth, on which you would use 303's "High Tech Fabric Guard".

Sunbrella is canvas, a fabric woven from organic cotton. It seems to be used for boats, not cars. It would also need the "High Tech Fabric Guard".

I've had great success with the 303 fabric guard on my top.

i also use it on my leather and textile motorcycle riding gear. The trick is to apply it on a sunny day and leave it in the sun so the product cures properly. i re apply every six months or whenever i notice the water not beading up as much as i like.
