Should you put any waterproof treatment on roof?

Should you put any waterproof treatment on the roof, if so what and where do you get it from.

Cheers

Autoglym does a roof cleaner and re-proofer in a two-bottle set (Halfords under £20 I think). They reckon every 6 months or whenever required. I used it once, works extremely well, gets rid of fading, bird shite, tree sap etc....spend the money!

[JonRB]

Yes! Fabsil or Thompson's Waterseal are good. Or if you've got more money than sense, there's the AutoGlym product.

Most people use Fabsil though.

EDIT: I see I was beaten to it on my reply!

Yes, it is. However, it is also very good on fabric, I'm told. And cheap.

Only those with money to spare! Thompsons Water Seal is often on a special offer at B&QHomebaseFocus. Paid £14 for 2 x 5 litre cans.

Just did my griff with fabsil spray - you can get it from any good camping shop - top stuff - the rain just runs off and is really good at sealing around the stiching etc - would recommend to anyone - about £6.00 per spray tin.

Hope this helps

The trouble with the spray is that it is difficult to avoid getting it on the rear screen and the paintwork (both not good). Fabsil liquid which you apply with a paintbrush is more controllable, albeit less convenient.

Or you could just pay your local friendly independant (Dave Batty in my case) to do it for the cost of half an hour's labour when the car is in for other work like I did.

I've tried them all and found Thompson's Waterseal worked for longer, was easiest (not necessarily easy) to apply and was cheapest.

No-brainer.

I've problems with the Autoglym product £13.99 from a locl factors.

Cleaner is pretty good although it left one small mark. I reckon I could have removed that too with a small scrubbing brush but I didn't have one to hand.

The water proofer seems very good though.

Roof looks very different to when I got the car now

a trimmer I knew once told me fabsil destroys the rubber membrane inside the canvas of the roof, so once you've used it you have to keep using it or the roof leaks waaaay worse than it ever did before... don't know how true that is but he sounded convincing ..!

'a trimmer I knew once told me fabsil destroys the rubber membrane inside the canvas of the roof'

That might be so for ordinary ragtops, but I assumed that under the cloth 'mohair' on a TVR roof panel was a slab of carbon fibre?

But hang on, that would mean you could simply rip the cloth off and have a carbon fibre roof, which might appeal to some PHers...

Only use 'normal' thompsons Water seal, they do an 'ultra' or 'plus' or some such thing - which is not recommended for canvas.
Do mine twice a year & its bone dry.
