When choosing the most appropriate type of varnish for your guitar, the following factors should be taken into account:

The finish you want. Do you want a glossy, satin or matte finish?
The resistance you need. Will you prioritise resistance to knocks or scratches?
The time you have to apply the varnish Do you have a lot of time or do you need it to dry faster?
The risk that may be involved in the use of each of them. Do you have a working environment that is well prepared for a possible fire?

Water-based varnishes are a good choice for guitars. However, it is important to assess what type of project you are going to carry out, and whether or not this product will be well suited to it. Although the gloss finish has been improved to a high gloss finish, it is more commonly used on guitars where a satin finish is desired.
