Thank you for all of your kind replies and advices on previous questions. But I have another one, and probably silly...
Since the body pieces don't match even in colour or grain direction, my question is:
My friend wants a stain finish, water based. So all products must be compatible, I think. One of the steps is to grain fill the body and neck. So, if I use this grain filler that has mahogany color, will it make the pieces match in terms of color? Will it disguise the grain?
