Which Thompsons Sealer?
Discussion
Coming from a completely different angle here - I feel that anything on a building that seals water in or out is a bad thing, and leads to more damp problems (cement render, tanking etc).
So, is sealing a hood a good thing? Wouldn't it be better to use a product that improves runoff, and combine it with a separate cover for when its parked up? After all, if you use a sealant won't it stop damp from leaving via the hood, and make the interior more susceptible to becoming damp?
I could be talking bollox btw.

I used the basic water seal which comes in a 5 litre drum, costs about £10ish. Its a red can and can be found in most DIY shops. Completely stopped my leaking roof, though on canvas it can require a couple of coats. There is also a water seal ultra though this is not recommended for canvas!!!
One thing to watch though is that it is VERY runny so be careful when applying it.
And to answer the other question, theres enough air gaps in a Chim to allow circulation with the roof being proofed.

If you want to do a good job don't use Thompson. Get a bottle of Fabsil and do a proper job. There are plenty of threads describing how to apply it.
Not true - Thompsons Waterseal is much better. If you read the tin if says its for Canvas and stuff as well as walls.
The one I bought was in a 1 Litre tin, liquid. Says on the back whether it's suitable.
Fabsil is not as good IMO. My roof never leaked after using Thompsons ...

Fabsil is a deeper penetration and good for many years. I applied Thompsons and it was leaking again after one winter. I applied Fabsil two years ago and it shows no loss of proofing. Even seagull poo stands up and fails to bond, just dries and falls off. My car is an every day motor so it needs to have a good seal.

I've used both of them too.. the exact opposite to what you describe. Fabsil "Gold" (the "better one) didn't really seem to get into the facbric despite using a whole spraycan on it, and got removed quickly when washing the car. Thompsons waterseal, applied liberally with a paintbrush really soaked deep into the fabric and has worked a treat for the last 9 months or so and is still going strong (car left outside for the winter). I will not be using Fabsil again for my roof that's for sure.
Each to their own.

Not used Thompson's but have used Fabsil a few times and it works a treat. Very east to put on with a paintbrush and seems to work very well after just one coat.
Some of the Thompson's advocates seem to end up putting on 3 or 4 coats to get the same effect.
M@H - As you have found out, the spray is crap and ends up getting everywhere. Need to buy the cans of Fabsil, should be able to pick it up in camping shops, or in Halfords (in the caravan section).

Used both many times on different cars. Fabsil works but doesn't last and is expensive in my experience which is why I prefer Thompsons .
You often need 2-3 coats irrespective of what you use as many owners don't seal them that often and multiple coats are needed.
BTW they use the same basic silicone technology.
Yer pays your money and takes your choice...
