I couldn't agree less wood inherently expands and contracts with different air temperature inkjet ink is a water based it can bleed in to just about everything specially with reducer dye you can get just about any colour you want for $8 in powder form and when dry wont bleed but you only have 4 basic colours Cyan, Magenta, Yellow and black in inkjet ink. that's last place one should go for colour the beauty with fabric dye is you can make it as strong or weak as you like and you can use any liquid to mix it with and is great for showing the grain, wood also excepts pretty much any finish one would want use because of the grain gives just about everything a great surface to adhere to sometimes too good that’s why you use wood binders for. As for 2k and polys they dry pretty much hard as a rock which doesn’t allow the expansion of the wood and after time it will pretty much crack and falls off in time. Ever had that chest of draws which the vanish is cracked and flaking off where you put your coffee cup but I guess whatever floats your boat
As for cheapo Chinese knock-off bought in a music store I take issue with, that’s pretty much what a
guitar kit is and selling a guitar with wax or oil makes its resale pretty much a no go. that’s just a plain ignorant comment as for the use of oil wax I don’t see to many manufacture’s using that as a finish guys like Warmoth who do some amazing finishes which are 2k Urethane finish and I would be stupid to say they look like cheapo knock-off.
I am old school I would use oil wax on a coffee table or my dining table not on a guitar, Gibson’s have been putting nitrocellulose lacquer on guitars since the 1902 as have fender which has been pretty much been phased out it’s a terrible finish when it comes to durability and shine replaced with Lacquer which will soon be phased out for 2k which is being phased out by water borne 2k’s. When I see wax or oil on a guitar I see that as the easy way out! lacquer requires you haft to know what you’re doing the planet is full off projects that people who have approached it thinking it’s easy and buggered it up.
Ill qualify myself am a tradesman furniture polisher and auto re-finisher for over 45 years i started my apprenticeship in a furniture manufacture till i was 22 and ended up in a crash repair till 2001 where i got into building race cars till 2014 when i had a M/C accident and now retied due to it, I have painted coffee tables to show cars used just about every type of finish you can think off and my hobby now is i do guitars which i enjoy quite a bit and keeps my clocking along and try to help guys who need it so you really cant tell me too much i don't already know
