Excellent Product

I purchased the Fabsil to proof a mohair soft top cover on my Triumph Stag, the product soaks in well and is quick and easy to apply. Pleased with the result as water now ‘beads’ rather than soaking through the fabric.

I use fabsil on our canvas Bell tents. I personally spray on the product as I find it the easiest. Used fabsil for as long as I can remember and have never had any leakage at all, fantastic product and would highly recommend.

Revived old flysheet

Having discovered we couldn't get a replacement flysheet for our ageing two man tent, reproofing the old one became a must.
Fabsili's easy to apply by brush and odour is minimal once dry. A 1 litre tin did the tent and left enough over to do two daysacks as well.
It kept the water on the outside during a recent rainy week spent camping.

Brilliant Product worth the buy.

Product is easy to apply, spreads much better than I thought and once applied you forget it is there until it rains. No leaks no issues. Great product.

Waterproofing my tent

I got this product to re proof my hi gear voyager 6 tent and porch,

This is a good product but doesn't go far... I used a full 1ltr tin on just my tent alone, although I did put mine an a spray bottle to make this easier for me. So maybe if I rubbed it with a towel it might have gone further. But seems very good stuff. make sure you are in a ventilated area though this stuff is potent!

Easy life

Ive used both the can and the aerosol sprays of this product and in my opinion the aerosols are easier for using on foot wear and clothing, bags etc, but for coating a tent or awning etc then the large cans go further when used with a garden sprayer, the spray isnt as fine as the cans and much better for that purpose. Both are good and do the job dries fast and so easy to use.Great product would highly recommend

I should have bought this first

After three coats of Nikwax the water still had no difficulty penetrating my Vango Icarus 500 so, in a last ditch attempt to avoid buying a new tent, I decided to give the Fabsil a try. I wish I'd bought this first! Just a few hours after painting on the Fabsil we had two days of heavy rain and I am pleased, and surprised, to say that we had no water penetration at all. I can't recomment this highly enough.
