Hi! This is my second post, so please be patient with me if this has been discussed before! And yes, I did try searching for the answers! I've had this ~1980 BC RICO for maybe 15 years now, and i've thought it was a great guitar. A bit neck-heavy maybe, but good tone and playability. My son unfortunately pushed it off its stand a couple of years ago which resulted in the wood around the pots cracking. It's quite a rare guitar, being one of only a few BC RICO's being made in Japan before the Rico Reed Co. decided to complain. After that they became known as BC Rich NJs - if anyone has more info I'd love to know! I'd like to restore it to its former glory - I have all the hardware - and need some tips: 1. Is it a nitro or PU finish? I've tried soaking one of the cavities with nitro thinners for about 2 min, which didn't affect the finish at all. I presume it's PU... 2. If I refinish in PU, will I need to strip the guitar completely? 3. If so, what's the best way to do so (I live in Germany so may not have access to the same chemicals as in the US). 4.Some of the damaged areas will need a bit of filling. What's the best stuff for the job? 5. What's the best way of getting that nicotine yellow hue to the white finish? Here are some more pics: Lot of questions, I know... Cheers!
