Which varnish is right for me?
Each painting needs to be assessed on an individual basis. Polymer Varnish is fine for acrylic paintings for indoor applications. MSA Varnish can be used on oil, acrylics and most other kinds of paints (always test first). MSA Varnish is also an ideal coating for interior and outdoor murals. It's excellent UV protection and tighter film and water resistance makes it ideal for such applications. GOLDEN Varnishes are NOT made for functional objects such as furniture, doors or floors. Commercially available products such as polyurethanes are a much better choice.

What would be the best varnish or varnish system to use on an acrylic painting?
Acryloid systems, IE. MSA Varnish is our favorite because for us it's the least likely to have negative results. It levels very well, so brush strokes and foam bubbles pop. We also like the film quality and its water clear nature in the wet state and cured. It's also a breeze to spray and it can be used on many materials.

Do you know of a product called MSA2, I think it may be a Lascaux product?
MS2A (AKA MS-2A) is a Ketone Resin Varnish produced and marketed exclusively for conservation purposes. It is produced by Howards of Ilford based on input from the National Gallery of London back in the 1950's. Over the years it was refined and reformulated, and discontinued until it was made by Linden Chemicals (now Linden Nazareth). It's very expensive (1997 it is quoted at $585 per kg.!), and it's also very brittle. Conservator, Elizabeth Joblonski provided this information and we can fax any more information you require. Elizabeth also commented on its ability to mimic the qualities of natural resins used in painting closer than other varnishes.
