TotalBoat Silica Thickener

Gonna thicken some 'poxy and make ""peanut butter"". JD always gets the materials to me quickly...they rock

Was very happy with this product. Used to make my gelcoat thicker.

I use it mainly as a thickener for vertical layups and also for ""gluing"" support pieces together. It's very uniform and mixes in easily.

I used the product to thicken the epoxy I was putting on so that I could slope it. It got thicker but I did not use enough and it still ran. Apparently, you have to use quite a bit to get it to thicken and become more solid than liquid but still pliable. Instructions would have been helpful. It makes it easier to sand but not by much. The epoxy is so hard, I had to use a grinder disk on my oscillator to lower some high spots.

This product is very fine and being silica I am very careful not to breathe when using, so I use less.

Well packaged, no leaks product worked great for small repairs, quick shipping, great vendor.

It does what it's supposed to, thickens real nice. A WARNING to anyone who wants to use this. WEAR A RESPIRATOR!!!!. Silica will kill you if it gets into your lungs! This stuff is a fine powder and gets everywhere.

Used to mix with TB 5/1 epoxy to make repairs to a 22 foot Columbia

Works for its intended purpose. Mixes very well with epoxy.

This is the best deal I've found on quart size silica thickeners. Great price plus free shipping because it's a Total Boat product. Everything I've ever ordered from Jamestown/Total Boat comes well packaged so it arrives in good condition. Jamestown has certainly been good to deal with everytime I've orded from them.

easy to sand , and cheap way of making volume

I use this product in hidden tang knife builds and in handle material depending on what is needed.

It works great as a fairing compound and makes sanding a lot easier.

Works great, makes very strong fillets, make it thick or thin. Light in color almost clear

First of all, Jamestown Distributors took care of me and for that I gave 3 stars. I took 2 stars off for having to go through the hassle of dealing with the following: I bought a 5 quart tub and when it was delivered, the lid had come off of the tub resulting in the filler spilling out all over inside of the box. Taping the lid down would have prevented this. In the past, I ordered a single quart and that was taped with strapping tape so why not this time? As for the filler, it mixes well with West Systems and does the job. To Jamestown Distributors: update your packing instructions for the order packers to always tape the tub lids.

Product opened and spilled during shipment ....caused me to breathe in when opening shipping container ... Otherwise product worked well.

Making minor gel coat repairs is a snap with this filler.

Perfect for thickening polyester resin to an vasoline thickness. Also mix with gelcoat then apply with a roller for a non-skid finish.

This product worked as expected. It is very light and tends to blow around if there is any wind when it is mixed.

Added in sufficient amounts to thicken the TotalBoat epoxy so it would stay put against the underside of the deck long enough to insert the G10 reinforcement into the repair opening. Blended well once enough was added to get the right consistency.
