I have a love-hate relationship with my guitar-refinishing project. Right now I’m in the “hate” phase.
Today I applied the 3rd coat of paint and, as you can see in the photo above, the paint has the appearance of lizard skin (not the effect I was aiming for). (High-rez photo here.)
Here’s my dime-store diagnosis:
A) My workshop window was open letting in cool air: it’s 5°C (41°F). Possibly the surface of the guitar or the paint — or both — were too cool for the paint to lay flat and smooth.
B) My PreVal jar had a small amount of paint and reducer in it — and I didn’t remove that when I blended new paint and a slightly different reducer. Here’s the reducer I was using initially:
As you can see, this is a “fast” reducer. For some reason, my paint-store guy recommended & sold me the “medium” reducer from the same manufacturer.
Forgetting to say a prayer to the patron saint of chemical compatibility, I blended my new “medium” reducer + paint + (remaining quantity of “fast” reducer + paint). Could this blend of fast and medium reducer cause lizard-skinning?
On a related note, have you ever wanted to take a guitar and thrash it within an inch of its life?
