General Finishes Waterbase Topcoat

About This Item

The best waterbase finish we've ever used.
A great gloss or satin finish in just one product, with no need for a sealer. Environmentally friendly, nonflammable.

General Finishes High Performance Topcoat is ideal for finishing musical instruments. It goes on without foaming or sagging, dries hard and sands easily.

  • Crystal clear, non-yellowing PolyAcrylic blend
  • Mixes well with ColorTone® liquid stains and waterbase pigments
  • Apply with a foam brush, or spray
  • Soap-and-water cleanup

1-quart can.

One can goes a long way! One quart will finish:
1 acoustic guitar body and neck
2 entire mandolins
2 to 3 solid guitar or bass bodies
3 to 5 electric guitar or bass necks
4 ukuleles
2 to 3 dulcimers
2 to 3 banjo rims and necks

Keep in mind there are many application variables: your spray gun adjustments, PSI used, how heavy the coats are applied, number of coats, and desired thickness on your instrument.

A little fussy but decent results if you're patient

By

Verified Buyer


Much less forgiving than solvent based finishes (ie nitro), but I was happy to work with it for the sake of safety and ease of clean-up. Best results spraying and drying at room temperature or above. Complete cure time of this finish is NOT 7 days though....each time I've tried to wet sand and buff it does ball up. General Finishes states in their tech data that the cure time is 21 days....best results when you can wait this long. You will get a better sheen if you let this cure properly, and don't rush it!

Too soft long term

By

Verified Buyer


I used this finish for 2 years and I am having a lot of trouble with customers coming back with finish problems, it is very susceptible to sweat, leather straps and even guitar stands will mark and soften the finish, not to mention the fact that it is just too soft in the first place. If I were only making guitars for myself or as a hobby then this finish would be fine but professionally it doesn't stand up well at all unfortunately

Response from StewMac


Hello Richard,
We're sorry to hear our that our General Finishes waterbase topcoat didn't work for you as you expected. Thank you for sharing your honest feedback with us. In the meantime, I've placed your suggestion with our product development team -- customer comments like yours have been the catalyst to many changes to our products. Please know that frequent use and moisture exposure (humidity,sweat) will cause this to wear and potentially soften over time. General Finishes recommend a curing time of around 3 weeks to ensure the finish is properly cured. Once again, we are very sorry for any inconvenience and thank you for your kind feedback.

Long term follow up

I have used this on three instruments now and I can say that it seems very susceptible to sweat damage. I have had to sand out pretty significant crazing and stickiness on neck and areas where players sweat might make contact with the instrument. Endurovar seems much more resistant to this problem. I also experienced this problem with KTM9. GF suggested that using epoxy sealer prior to finishing with high gloss top coat may have contributed to the problem. Hope this is useful.

First Try Looks Great

By

Verified Buyer


I had been a long time user of KTM-9 which is no longer available. When you've dialed in a finish material and have a repeatable system it's a rude shock when the product vanishes. I bought a quart of the General Topcoat hoping for the best but expecting a surprise or two.

My first use was on a re-top and re-fin on a wrecked J-200. I spray with an HVLP unit using a decent quality Fuji gun. I followed the schedule StewMac provided and I'm happy to say all went perfectly. I used a total of 12 coats waiting the 90 minutes between applications over 4 days. I had no runs or glitches at all. 7 days of cure then wet sanding from 400 through 1200 and normal buffing produced a fine, smooth gloss.

I found this finish to be easier to use than KTM-9. It had no tendency to run and did not tend to dry in the nozzle between coats like my former finish. I sprayed in 80 to 90 degree weather during the Arizona monsoon season with humidity in the 50 to 80% range.

The completed instrument looks the same as my previous finish. I expect it to hold up well but I can't rate it at 5 stars until I see how it looks in a year.

I'll likely stick with this for the next couple of builds. So far, so good.

Interesting stuff. Best to put more than three coats on (as recommended) other than on the front which should have as little as possible. Then buff with compound. Great finish.

Great Product most of the time

This beats smelly lacquer, dries a little slower, and I have had some mixed results. The weather generally is the biggest issue, make sure it's warm enough when applying. I would definitely recommend this product for anyone who is as careless as me, that might not use a respirator the whole time, much less toxic than nitrocellulose.

GREAT PRODUCT!

By

Verified Buyer


10 years ago I produced a two and a half hour DVD set on the first generation of water-based finishes. The finish was OK but was fraught with foaming and drying problems. This new water-based finish really hits it home. I just finished a guitar using foam brushes and with the right technique, it comes out with a deep shine and very hard finish. I use water-based finishes in my instrument building school to provide students with a safely applied finish and easy-to-touch-up classroom experience.

Great Stuff!

I decided to give this a try after using nitrocellulose lacquer for years.

It works great, buffs to a great shine.

There is a learning curve if you are used to lacquer, cannot apply it as thick it runs easily. On my first attempt I sprayed a thick wet coat as I was used to with lacquer, and had to start over from scratch.

I am happy with the overall result, but it is not as hard as lacquer, it will dent easily so giving it only 4 stars

So Far So Good

I have been spraying this with the Stewmac $35 gravity gun and am very pleased so far. No drips, no sags, no runs and a beautiful look. The stuff goes on a little milky but dries clear. Add a drop or two of amber to warm it up a bit. I am not an experienced spray finisher but can't say enough about how easy this is. Seems to go on a lot easier than KTM-9 but that might be the new spray gun.

No brain damage yet either...

Not hard enough by itself for instruments

By


I have used this a lot for custom mill work that isn't interacted with on a regular basis. It marks very easily. I have also done extensive controlled testing with nearly the entire line of General Finishes topcoats.
I do also build guitars, and if you need to use a GF product, the hardest and most scratch resistant is the Enduro-var and the Conversion varnish. Endurovar is challenging to spray verticals, but the CV is easier. More prep time with the 2 part CV though. In the end though, they still don't get hard and scratch resistant enough for a guitar.
That being said, I will build coats with one of these 2 products and then final top coats are done with an 2 part auto clear.
