Behlens - When Only The Best Will Do
Just like the title states: when only the best will do! Behlens makes some of the best products on the market (in my opinion, anyway), and this vinyl sanding sealer is one of them! I use this product (and other Behlens products) exclusively, when building, finishing, and refinishing guitars. It has yet to disappoint! When used properly, this product does exactly what it’s suppose to do. Very easy to work with, and very forgiving! Wether you’re a beginner or a seasoned woodworker, this product needs to be in your arsenal! If I could give it 10 stars, I would!

Great for raw wood guitar bodies
I bought an un-finished bass guitar body of solid Mahogany with a Spalted & Flamed top. The wood is quite spectacular as the first pic shows.

After much sanding, I applied one coat of Behlen Vinyl Sealer for Stringed Instruments. Then, the next day another coat. The result show in pic 2 is a beautiful color and ready for Lacquer. Its just what I was hoping for.

Beholden vinyl sealer
I always use it as a base coat under the Behlen nitro finish on the guitars I build. All their finishes work very well

The best foundation for a guitar finish!
This is great stuff, it sprays well, covers well, sands well. And it dries very fast. Sand it back and recoat if necessary, then follow with Behlens toners for color, then Stringed Instrument Lacquer, wet sand then use their Buffer's Polish to finish it up and you'll have the best looking finish you can get from a spray can.

Great sealer
I use Behlen Vinyl Sealer in my guitar finishing process. I like it much more than sanding sealer. I use it on alder, maple, mahogany, ash, whatever. Allows me to build up coats quicker.

Great Lacquer
I build Jewelry boxes for a hobby and most of the products, including most of the exotic wood, I buy from Rockler. I like using Rockler because they have a good assortment of product and their handling and shipping are exceptional. The Behlen Lacquer is an outstanding finish for my projects.

Very good Lacquer
I make jewelry boxes for a hobby and I have found that the Behlen sealer and lacquer are some of the best in the spray variety.

I had been having a heck of a time making these guitars like they were professionally refinished. Sanding sealer seemed to really bring out the nitro I was working with.With my guitars I don't bother with nitro. In fact I use poly on may of mine. I didn't think sanding sealer was meant to be the clear coat but it seemed to look the best. I know there's a water and lacquer base but what else is in that stuff/ Luthiers insist on starting with a grain filler. Can You recommend one?
Kurt M on Oct 28, 2016
Is this pre catalyzed? Would you use this under a 2K urethane, or only under lacquer?
Bravin N on Jun 3, 2019
BEST ANSWER: This is not pre-catalyzed. Mohawk (Same company as Behlens) makes a pre-cat lacquer. I’ve used both, and the pre-cat works wonders (better than the stringer instrument lacquer)! To avoid interactions between products, a good rule of thumb is to use the same product throughout. If you use lacquer as a base coat, use lacquer as a top coat, but make sure you also keep it in the same “family” (nitro with nitro, enamel with enamel, etc.). Hope this helps!
Do you put the sand and sealer on first or after the color?
Gary E on Jan 4, 2017
BEST ANSWER: color always after the sealer coats, you get a much more even look.
I am looking for a satin finish for a guitar am working on.....do you sell this or what do you recommend ???
teresa b on Feb 1, 2019
BEST ANSWER: This product is a heavy build sanding sealer. It’s useful for filling grain before final lacquer finish is applied. I recommend it when starting with unfinished wood because it fills and builds faster than lacquer. It’s easily sanded and makes a great base for the lacquer.
