Waterproofing my 987 hood

I want to waterproof the soft top on my 987.
I have 2 options in my workshop, but, TBH, am unsure if either are suited for a Porsche roof.
The first is an aerosol; Graingers 'Fabsil’, the second; Starbright waterproofing with PTEF (yes PTEF not PTFE).
I have successfully used both on the covers of boats, but have not, until now, fpund the need to use them on a car hood.

My question is simple;
Can I safely use either on an original Porche soft top.
Any advice gratefully received

I used to use Fabsil on the TVR roof and it worker well.
I now use Nanolex on the 981 roof and my wife's Audi TT and get great results.
Not sure about the Starbright though not heard of it.

I've used Fabsil for a couple of years with no ill effects. You will need to repeat the treatment at least a couple of times a year but it certainly works. After applying Fabsil you will find that water just "beads" on the surface.

My Boxster lived out all the time ... Fabsil spray seemed to work very well on the hood and when the excess was wiped off it seemed to make a good job of cleaning it ...

I found the Autoglym convertible clean and protect kit worked extremely well on my 987.Follow the instructions carefully,the cleaning phase lifted loads of grime off and once the sealer was applied rain beads off very nicely,has stayed this way for several months now.

I've used Fabsil on a Porsche hood and a TVR. You can get big tins of it in liquid form (ebay / camping shops / screwfix) and brush it on. Less messy than an aerosol in my experience, and ensures even coverage.

Someone in the PCGB suggested I tried Fabsil Gold. The tin, rather than the aerosol which tends to get all over your glass. I brush it on giving it two coats - once in one direction and then allow to dry. I then give it a second cost in the other direction. It’s amazing stuff. The water beads beautifully. Brushing it on allows you to do a really neat job with zero overspray and maximum coverage. I use two brushes as well. One for the larger areas and a smaller one for the edges. I pour a smallish amount of the liquid into a smaller wide container to dip the brush in.

Recently used Autoglym Convertible Soft Top Clean and Protect which came out top in a car mag survey ....... it worked very well.

OK
For almost a month and 3 windows later (1 from the South of France) I finally have a working window in the drivers door of the car. This is such a joy, given that for 2 weeks, the glass was in the passenger side footwell, the door trim in the boot and cable just hung from the inside of the door.

Anyway . . . .waterproofing.
Very many thanks for all the good advice.
I have given the top 2 coats of Fabsil, applied with a sponge.
It rained (a little) late last night and the Fabsil seems to have made a marked improvement.

However, to be sure, I plan to spray a final application onto the roof, during the next few days.
I have a load of old towels, rejected by SWMBO, but perfect for protecting paintwork and glass.
I have a roll of yellow Frog Tape, which I can use to mask the rear window seal and the hood front bar.

I just need a still warm morning.
