How To Refinish Musical Instruments With Spray Chrome
If the musical instrument that you love has become rusty and cracked, it is time for you to refinish the surface. When you refinish your musical instrument, it will both make it look better while also helping it to sound better, too. The new finish helps to improve the sound of your instrument.

Spray chrome is significantly less expensive, doesn’t use toxic chemicals and is much faster. Soon, your instrument will look as great as it did when it was brand new, and you can play away as you wish. Read on to learn how to refinish musical instruments using PChrome.
This process will work for the following applications:
- brass instrument refinishing

- trombone refinishing
- And So Much More!
Remove the old finish
The first step you’ll have to complete is to strip off what is left of the old coating. You can do this with extra fine steel wool. If the finish is very stubborn, you can wipe it with paint stripper and then use the steel wool on it. It should wipe away easily. After you have removed the coating, thoroughly clean the instrument and dry it completely.
Mix your chemicals
Your PChrome kit comes with some chemicals, the chroming process and your top coat. The base coat chemicals are labeled in bottles with the letters S, R, D and W. Mix the PChrome S solution with deionized water at a ratio of one part of the solution to 30 parts of the deionized water. Label the mixture’s bottle to prevent cross-contamination. Next, mix the R and D solutions with deionized water in the same ratios, and label their bottles. Finally, mix 4 parts of the PChrome W solution with 30 parts of deionized water.
Apply your basecoat
Your basecoat is made out of a combination of chemicals that also came with your kit. Mix together equal parts of your Permalac 2KA basecoat and 2KB hardener. Adjust the fluid setting on your spray gun so that it releases a fine atomization of the basecoat. Use 28 to 32 psi and spray your instrument so that it has a smooth, even coating. Any mixture which remains after 90 minutes should be discarded. When you are finished applying your basecoat, make certain to thoroughly clean your gun with acetone or lacquer thinner immediately afterward.
Prepare your instrument for sensitizing
Next, prepare the instrument for sensitizing. To do this, spray the #87 solution all over it. After letting it sit for 30 seconds, spray it liberally with your W solution.
Chrome your instrument
Before you get to the metalizing part, you first need to spray the D solution all over your instrument. Do this using your single-nozzle spray gun. When you spray it, work your way from the bottom to the top to prevent beading and streaks. Then, repeat the application of the W solution followed by the D solution, and rinse your instrument thoroughly with deionized water.
Now, you’ve arrived at the fun part! Without allowing your instrument dry, immediately metallize the surface. You will feed in the S and R solutions into your dual-nozzled spray gun and spray your instrument from the bottom to the top, using slow and steady back and forth movements. Continue applications until you have reached the desired level of shine. Then, rinse it with deionized water. Dry it immediately by blowing it off, making certain not to leave any water droplets behind. Let your instrument rest for a minimum of one hour before proceeding.
Apply your top coat
Mix your top coat together by mixing equal parts of the Permalac 2KA top coat and Permalac 2KB hardener. For every 75 ml of the 2K mixture, add 1 ml of the violet top coat to counteract any yellowing. Then, spray it on using the same gun that you used to apply the basecoat but at tighter settings so that the top coat comes out in a fine mist. Apply it all over your instrument. Let it dry for 48 hours. If you’d like, you can apply a second top coat application at that point. Make certain that you clean your guns thoroughly.
