I don't think he was talking about painting the bike. It sounds like it when he said 'strip', but I think he was talking about taking it apart.
If it ain't broke, don't worry about it yet. Get it to where it works, then little by little start taking components one at a time off so you can clean and lube them.
Spray WD-40 on bolts that you plan on taking out, but away from your chain and bottom bracket (the WD-40 would remove the lubricating grease from those). It will help a lot when is time to take them off.
Look at the stuff that if left unattended will further damage the bike; loose spokes, loose bottom bracket, play on the wheel hubs, and anything that is not tighten down.
