[Mapearso]

I need advice / suggestions on how best to preserve the wood bed on my truck

It is the original wood and is dry and warped, with a couple cracks but not TOO bad

I DO NOT want to replace the wood (its a driver / patina truck). I just want ideas on what to do with it

Just leave it alone? Boiled linseed oil? Spar varnish??

Thanks in advance guys
