Hey all, I recently picked up what I believe is a 1991 Trek 6000 at the local bike kitchen.

As it was when I first saw it.





I removed the cheap-o wheels, bars, seat, rd, and shifter.



Next thing to do is to remove the rattle-can (disguise) paint job on half the frame/fork.





To remove the paint I tested out using Zep 45



my dad tried brake cleaner on the chainstays



and gasoline on the seatstays



Brake cleaner works the best, so we'll work with that once we return from our trip.
We'll probably have to get creative with the decals, though, so we don't lose them.

Rivets everywhere.







I'll also be switching out the steel fork for a 2000 RockShox SID

Nice find! Good luck salvaging the finish. You might also want to try graffiti remover, takes off the spray paint and retain the old layer of paint.
I picked up a 91 Trek 8000 recently off CL, essentially the same frame, different components. It's a very light frame and uniquely constructed. Too bad it is too big for me.
You don't see these early aluminum Treks too often here. Be sure to post your finished Trek in our Vintage mountain bikes thread!

BTW, if you don't have a use for that rigid Trek fork, PM me. I have an old Trek 930 steel mtb about the same size that's missing its steel fork.

That was my wife's first mountain bike. She loved it.
