Seam sealer or diy silicon? I'm about to start so....

I'm pretty sure you meant mineral spirits.

When you say silicon from Lowes, or whatever hardware store, are you talking about plain old 100% silicon caulk? Like in a tube?

So 4 parts mineral spirits to 1 part silicon, mixed and painted on silnylon seams...

Yes, 100% silicon. Clear

This works great.

I bought some of this, but haven't opened it yet. Is it ready to go, or does it need to be thinned somewhat?

And to clarify it 4 parts to 1 part by weight not volumne...IIRC...

Actually, in this case, they are the same thing, given the specific gravity (is that the right term?) of each. Anyway, it's close enough, as you can mix anywhere from about 10-to-1 to 3-to-1 anyway, so no big deal being exact.

And I'll add my vote to DIY mixture... much cheaper, you can make it thick or thin as you desire, it'll save for a while (though not more than a few days or weeks before mine gels), and you can make the volume you need.

I buy the cheapest silicone in a caulking tube at Walmart. Same for mineral spirits. And mix as someone else said, in a jar or bottle with a few loose nuts. Put on some disposable gloves and paint or wipe on and wipe excess off. Hang to dry, which is pretty darn quick. Repeat a time or two. Test. Works great.

Just wanted to add my 2 pence on the DIY method. It works great, but for the second time now, my cheap arse walmart bought sponge brushes lost the head (brush part) in the mixture. Could be that I use it thick (4-1 mix), but I'm starting to think that I will just don some rubber gloves and use any clean sponge. I don't want this stuff all over my hands and for the second time it happened because the brush gave out.

i know this is a old thread but i'm going down the same route, so far this is what i have found

What's the difference between GE Silicone I* caulk and GE Silicone II* caulk?
GE Silicone II* caulk is what's called a "neutral cure" silicone, which means no acids are released during the curing process (as there are in GE Silicone I*). This enables GE Silicone II* to adhere to a broader range of substrates such as plastics, concrete, and metals. Also, the odor of a neutral cure silicone such as GE Silicone II* is much less offensive than an acid or acetoxy cure silicone such as GE Silicone I*.

After doing some intense research after work i found this, it seems that acetoxy is full of acid, others can be full of alkaline. GeII stuff seams to be safer.
