Silicone sealants

Pretty sure I know that "acetic acid" smell you are talking about. I think it is is the cheap silicon stuff that is not waterproof or paintable.

 

I have worked in the past with pickling onions and hate that sweet ,sickly smell(esp with onions).

The intended application is to mix it with white spirit to make waterproofing solution. I bought some Diall clear GP silicone sealant - mixed it at the rate of 5g sealant to 50ml white spirit - and it waterproofed a garment fine until it was washed in non-biological washing powder at 30C. I know the commercial waterproofers allow washing up to 3 times before re-application is required.

 

With the stuff washing out first time I'm wondering if there is a more resistant silicone I can use suitable for this purpose.

 

This is just an experiment to see if I can make a useful fabric waterproofer cheaper than the commercial stuff..
