Fabsil

[wombat88]

Is there any point in putting on a second coat of Fabsil?

Would it improve the water resistance of the material in question or simply was the first coat out?

Not really ,unless you didn’t get it all wetted out first time round

It helps sell more Fabsil? Otherwise I never saw the point in that instruction either. One good coat soaked well in does an admirable job.

Just fabsilled my canopy with two coats applied by brush. It worked ok apart from one largish area that lets the rain through. I can't explain why as this area was treated the same as the waterproofed area.

Water tends to collect in the centre of the upper panel of my old sprayhood. As the amount of water increases the panel sags more and the depth of the puddle increases. Eventually it starts to soak through.

Treatment with Fabsil stops it for a while but it is not a permanent solution.

This winter I plan to sew a large patch of acrylic canvas or maybe some PVC polyester fabric over the affected area in the hope that will stop the water soaking through.

However the real problem is that the top of my spray hood is not sufficiently curved so as to prevent water puddling. The only answer to that is a new sprayhood with a more curved shape but that means new hoops and also my tonneau cover and cockpit enclosure might not fit the new shape.

Poignard, as a temporary measure would it be possible to put pipe insulation along the top of the hoops to tighten up the canvas a little to prevent the sagging in the middle?

That’s an idea worth exploring. Thanks.

I use grp tent poles or, more recently, aluminium ones to curve and tension my sprayhood and cockpit tent. Yeah, anything to stop puddles will be much more effective than trying to waterproof the problem away in my experience.

Btw, I found Fabsil Gold more effective than ordinary Fabsil when I was living on board in the UK. More expensive but more effective

+1 for Fabsil Gold. I found the ordinary version started going porous before the end of the season, but gold lasted until the beginning of the next (boat in all year round).

I'd be interested to know how you have arranged that.

Are these tent poles permanently fixed to the sprayhood or something you clip on after you have put the hood up?

I use these sort of poles

in a hoop to push up the flat centre of my sprayhood from underneath.
Which reminds me that I haven't done it yet. I reproofed and refitted my sprayhood last week with a Spanish product that seems like Fabsil (I'm in Spain.) I remove the sprayhood in summer as it traps far too much heat.

Thanks for a good idea. A length of flexible pole, perhaps with a piece of pipe insulation as recommended by Lucy to reduce chafe.

Used three layers on my wife's SAAB convertible, almost poured it on initially as it soaked it up then the third layer spread easily, took a while to soak in and dry so job done. Great catchy marketing name! FABSIL!
