finish repair with crystalac brite tone

[revans02]

Hey everyone - i am finishing a ss guitar with crystalac brite tone. This is the second time i've used it and i really like it. I am brushing the finish on.  Unfortunately, i have a couple of spots i sanded thru on. Any advice or experience with this finish and dealing with these? I'd like to be able to do a spot repair but don't want witness lines.

Thanks in advance!

I've used it about 15 times and have it down pretty well. That being said, I'm also good at repairing spots that I sand through. The biggest issue is did you use their sanding sealer? If you did, you want to rough the non sand through areas next to it and put on a coat or two of sealer. If you don't, it won't blend in when you apply the top coat. Come back with a two or three coats of clear and let it cure for a few days. Use a small block with1,000 grit sand paper glued to it. Don't wrap the paper around the block or you will sand through again. If the areas are on an edge don't use the block. Sand it dry so you can see how far you need to go. 

You will most likely have witness lines at this point. After leveling, let it cure for a week or so and sand up to 2,000 or higher. Compound it out and it should be good to go. If you still have witness lines, just let it cure longer and hit it with compound. 

Now, to really do it the correct way, you need to use an airbrush to apply both the sealer and clear. You don't need a high dollar airbrush. The airbrush will lay the finish on so you don't have to deal with high edges if you brush it on. You don't need an airbrush, but it makes life a lot easier. When I use an airbrush, I don't have to use a block to level it, as it's pretty much level to start with . 

Hope this helps.

Thanks, i am encouraged that i don't need to recoat everything! My base coat was shellac, which i will apply to the sandthru to get the right color.
