I grain filled and then sanded flat and everything looked great. Once I started shoot the clear, however, I saw this:

(Image embedding is still not working for me, so I edited to use a direct link)

Can I shoot soon sanding sealer over this to help build it up so I can get it flat?

Or should I just keep shooting the clear until it's built up?

Do I need to strip it and redo the grain fill?

This is the second time I've done a grain fill, sanded it and it looked flat, then when I started spraying, I could see the grain. What am I missing when it comes to grain filling?

For the record, this is a mahogany body and neck, if that makes a difference.


Thanks,
Chris

You have to use the actual image address. In Imgur, right click and open the image in a new tab. Copy the link in the address bar.

It looks like this:
Code:

Then use the IMG button in the reply window to make your image show up, like this:



I added an "L" just before the ".jpg" to limit the size of the pic. Otherwise you'll blow out the page. If it's still too large, replace the "L" with an "M".

Mark forgot to answer the question, LOL, but now I know how to size my pics also.

Welcome to the joy of grain filling. There are a couple schools of thought on where you are.

1. Sand it flat again and continue clear coats.
2. Keep shooting and sand flat after you have enough on there to get to flat.

You could fill the grain again now and go back to clear coats. If it is still really deep, that would be the better option.

OR... Get you some AquaCoat clear grain filler. Love this stuff. I use it anytime I run against grain such as yours. I've used on bare wood as normal filling, in between sealer coats, over stain or dye application, before/after primer application, between top coat application. It just works in about every case you might face during the finishing process

Lon,

Is this compatible with nitro and 2k?

I didn't forget, just left it for someone else. I'm a busy guy. Wink

Thanks! I've ordered some AquaCoat and am going to give that a shot.

As for image embedding, I'll try an experiment and show off the top of the guitar, which I think is looking pretty good.




[Edit: Looks like that embed worked!]

Thanks,
Chris

You know, I've had issues with Aquacoat, Timbermate and Zpoxy by themselves. Could never get the grain fully filled. The only thing that seems to work perfectly for me is a few rounds of Timbermate followed by 1 or 2 rounds of Aquacoat.

Just my 2 cents.

Ralph, I've only used with nitro with no problems. Mark may be able answer your query on 2K, I've never needed it when I've done a 2K finish

I've never used Aqua Coat.

But with other water based fillers, I've found that I get better results with thinning them to like a melted ice cream consistency and brushing on rather than spreading like a paste.

I concur. I used aqua coat to fill korina, all nitro finish. nitro sanding sealer, nitro paint (Bill's surf green), nitro clear. year and a half later, still good to go.

I've had good luck using 4F pumice mixed into Timbermate or Famowood grain filler.

I never measured it out. I just mix some into the grain filler before I work it in. Whatever it does seems to help keep the filler from shrinking.

Never tried Aquacoat but it sounds pretty good.

I have never had to grain fill the back of a neck.

+1 on AquaCoat. You can apply it over an initial finish to "save" the grain fill. Just did this on an ash strat body that received 3 initial pore-fill coats and STILL had some grain showing after the first color coat. I used AquaCoat, sanded, applied AGAIN, sanded it, and then played on.
