hood water proofing products

[phildingle]

hi, can anyone recommend a good hood water proofing product? i have water seeping through the mohair fabric around the rear window, i have heard a few bad reviews of some of these products and dont want to apply something that will ruin the look of the hood, cheers.

I use Fabsil which is very good but you need to get the paint on type not the spray on.
It is painted on with a paintbrush but it is like painting on water! 2 coats is usually enough every 6 to 8 months if it lives outside.

Renovo is also widely used & they also make cleaner & restorer products.

try using fabsil,tvr specilists recomend it.

Thompsons water seal does the job

I thought that was what you put on a shed (er, the wooden type)

Autoglym fabric hood maintenance kit user here - I do it every 2/3 years, never leaked a drop, it is clear and does not fill up the mohair grain (unlike some others).

This old debate goes on, Thompsons do not recommend their product for canvas type materials, it is a brick work sealer.

Fabsil is specifically formulated for flexible canvas like surfaces.

It is worth while taking the time to properly cleaning your roof before application because silicon sealers are waxy and over time become contaminated with road grime.

This is my method for clean and reseal using Fabsil

The spray on application is annoying, as any over spray needs to be dealt with.
Very early in the car's life I started using this (after I had a minor leak experience), and never suffered a leak again.
There may be better options, but this worked for me.

Tip it into a cup and brush it on, that is what I have always done

I used this a few times, but switched to Renovo from ACT. Much better, adds in a UV proofer.

Also Thompsons may actually melt/degrade the roof (although I personally have not experienced this). Only ever used Renovo on my Griff.

Prolonged my old original black roof a further 3 years past its sell by that gear dead easy to apply a blinding product IMO and recommended to me by a fellow Tivver many years back it smells like a similar silicone based product and does not damage the fabric in any shape or form, in fact it does the exact opposite "Does exactly what it says on the can"

It actually states recommended for canvas on the tin so I think you're mistaken.

Thompson customer support wrote an email to someone on PH last year that stated (I paraphrase) "Thompson waterproofer is not recommended for application to flexible materials. In the event of damage Thompson would not accept liability". A copy of that email was posted on PH.

I still struggle to understand the issue though. Thompson waterproofing is for protection on building materials and is traditionally sold to the DIY market by B&Q & the like. Fabsil is specifically formulated for flexible fabrics and is sold by camping suppliers. It's obvious to me that Fabsil more closely aligns with application to a fabric hood. In the end I'm no expert but that's the very reason that I choose Fabsil. I can trust that Fabsil is formulated to waterproof flexible canvas. The silicon is dissolved in a solvent to enable distribution of the silicon, I don't have any confidence that Thompson use solvents that won't harm the glue or substrate materials use in my roof sections.

Two types of Thomsons out there, the origional in red and white cans from memory that works well on fabric, and the newer Ultra that I would not use.
