Acoustic Guitar Construction

Hi Dave hope you are well. I have a question for you as usually.
If you are in the process of doing the Tru- Oil and you see a area where it needs more wax free shellac is it too late or can I redo that area and then proceed with the Tru-Oil??

I see where TO makes a sealer/pour filler also. Has anyone ever tried it on a guitar?https://shop.birchwoodcasey.com/gun-sto ... oz-bottle/

No I had no problems with the TO I love the product.
I just need to find another pour filler maybe that Zinnser Seal Coat? I also want to make or stain the Mahogany a darker color on the next one I do.
Thanks for all of your help.

Hi Dave I have a couple question to ask you if you don't mind. I read somewhere on here where you said you were using another pore filler that you liked better, but cannot find the thread. Can you tell me something about it or where the thread is? Also just for talking everybody said you don't have ...

Thanks Dave you are the man.
Happy Thanksgiving to you and your family.

Also Dave I still have a couple spots on the top if you put it under a good light that could use a tad more filling. If I did do a 50/50 would that help to do that??

Dave I have 15 coats on the top and am happy with the finish. I know you like that hand rubbed finish and so do I but I was wondering if I should do a final coat of TO and Mineral Spirits mixed 50/50 What would you do?? Have you ever did that and if so which way do you like the best?
