Coating cast glass

I've heard and/or read about coating castings (Gaffer in this case), especially after sandblasting to protect from finger prints, oils, and what not. Obviously there's Liquid Lust'er and I've had a thin coating of Hextal suggested. Years back I read on this forum (I believe) of a common clear bathroom sealant being used.

While I may take my current casting to a polish, I'm interested to hear others experiences, whats good and what not.

I've been playing around with a new (for me) substance, Liquin. It's a lacquer-type outer coating for oil paintings, a lot of online art suppliers stock it.

Has worked well so far the handful of times I've used it on sandblasted glass pieces, but it needs to be applied carefully - I messed up one piece by trying to use a paper towel to wipe off some excess and getting little paper particles stuck on the surface (Going to need to re-sandblast that piece to fix it).

Going forward I am planning to heat up the liquin a bit in a double boiler beforehand to thin it out, and use a soft brush to apply it, to try and get a more even coverage


Edit: Link to another useful thread on this topic from 2011 that Dave unearthed: Sandblasted surface coatings

After figuring out the right search terms, I found the thread from 2011 under "Sandblasted surface coatings".

Here ya go, https://www.bullseyeglass.com/method...?articleid=766 .

Bought it, but have yet to use it. Personally I like Hxtal thinned with acetone and air bushed. It's kind of a huge pain, but the results are perminant.

Air spraying Hxtal gives me the willies. Only do that with superb ventilation. If I say what I really think, I hear from their lawyer.

Agreed. I haven't done it in some time, but always under a hood and with a respirator. You can apply thinned by brush and still get a lot of detail, but spraying lets you retain the blasted texture, if that's what you're after.

I use it all the time on sandblasted bullseye. Good stuff. And surprisingly, BE's price is ok.

Has the Clean Shield withstood the test of time? How old is it?
