@Robbyrockett2 Damn guitars are something else , from the info u gave me , but thanks again mate I know 0% about a bass gitar , i want to learn and play this one when done but my knowledge is very low on knowing the brand nor the model. Someone gave this to me , and i cant find any serial numbers , brand names etc. So i don't know wich clear there is on the bare wood itself. If i go with autoborne sealer straight into the cracks and over the clear, i can not fill those cracks up (doesnt fill as far as i know), i was thinking about making a airbrush design around the cracks on purpose but if this happens for a customer's gitar iam 100% fucked. But i will have a look at the Shellac too. And i didn't know about the feel the gneck needs to be too, thanks for all the info The 2k clear i am using for the project is is a polyurethane (air dry able) , pretty cool to test this one out , gonna do some test panels first.
