Spraying a guitar?

Question

I'm refinishing an electric guitar. However, throughout the spraying process (grey paint), the paint can randomly ejects little paint lumps onto the surface. Then, I have to wipe all the paint off and try again, hoping I can finish before any lumps get sprayed.

I don't understand, since it's a brand new can. What can I do to make the paint go on perfectly smooth?

Answer 1

Instead of wiping off the paint, wait for it to dry then lightly sand away the high spots. I no longer use spray cans of paint unless there is no way I can easily get my spray gun to the part I am painting. If you buy a HVLP conversion gun and a Compressor to run it you will be able to turn out high quality paint jobs. There is really no way to prevent the little lumps from landing on the guitar so all you can do is sand them away with 300-400 grit wet/dry sandpaper lubricated with water.

Answer 2

Sounds like you may need to strain your paint. Use a nylon stocking and pour the paint into it over a clean pail or can, this will take any lumps and other debris out.
If you are spraying thin the paint before putting it into the sprayer, this will help too. If you don't have a spray booth, build a makeshift booth with a staple gun & plastic sheets in a place where there is little or no dust. Wear a respirator mask and goggles when spraying. Spray at least 12 inches away in sweeping motions stopping the spray after each pass. Do not over spray it, it will what the call orange peel. Spray 3 coats or more depending on the finish you want.

With my experience with paint cans they are a real pain to do fine work with..Your best bet is to start spraying about six inches away from the edge and make a pass and don't stop while you make the pass till you are over to the other side.After a few passes wipe the spray tip to remove and build up.And when you are painting something that needs a nice finish with my experience i have learned that once the can is more than 3/4 empty stop using that can because the pressure is no longer really that good to be even.You may end up buying a few extra cans the end result will be well worth it.And buddy keep in mind that different paints will affect the sound and tone of the guitar..

"Spitting" often occurs when the can is a different temperature than the environment than where it's being used, or when the can isn't shaken enough (you should shake it initially for at least 5 minutes), or when the paint is old, or when the nozzle is cheap or of low quality.

No paint goes on perfectly smooth and will require some pretty significant time rubbing it out with varying grades of compounds, so be sure you get enough clear coat on to avoid rubbing through to the color... you ARE going to put clear coat on, right?

This is one reason that a professional job costs so much money... correct equipment =good job.

Answer 5

This is my question - My friend was just over yesterday and watched me clean my acoustic Yamaha. He's very knowledgeable.
I would like to share with you what I learned.
He advised that it is important that proper materials are used when cleaning or refinishing a musical instrument because this have a strong effect on how your instrument will sound. If you can afford it, it should be done professionally. If you want to do it personally then.... in answer to your question: you should go to the local music shop, have them look at it and get their personal advise on how and what products to use for refinishing.
Good Luck!!!
