Removing lettering from Bachmann On30 passenger cars requires a different approach than the freight cars. I didn't want to take the cars apart at this time so a method other than using Polly Scale ELO would be needed. I had read that the lettering could be removed with a pencil eraser but I found the eraser ineffective. I found 2000 grit wet-dry paper at an automotive store and it works very well.
Bachmann On30 freight car lettering is easily removed with Polly S Easy-Lift-Off and scrubbing with a toothbrush.
2000 grit paper is available at automotive stores. Used wet it will remove the lettering without adversely effecting the finish.
A soft wood stick about 1/16 thick x 1/4 inch wide is needed. Coffee stirrers are the right size. Balsa will also work well. Cut the sandpaper into a 1/4 wide strip and bend back one end.
The sandpaper is wrapped around the wood strip and advance as it wears out.
I used this method because the car would be left assembled. The lettering is on a strip without any riveting or other protuberances so is easy to sand off. Chemicals would play havoc with the "window glass".
Wet the sandpaper and start rubbing on the letter. I do one letter at a time.
After a few rubs the letter will start to come off. You can feel the letter as it is being sanded off.
Turn the stick sideways and finish the remaining pieces of the letter at the top and bottom.
The lettering is completely removed from the car. Advance the sandpaper around the stick as it wears. I advance it for every new letter.
The surface is dulled from the sanding but that will disappear with the application of gloss finish in preparation for decaling.
The numbers on the sides can be removed the same way but require an additional step.
The lettering after sanding remains in the siding grooves. This is why I use ELO on freight cars it removes the lettering from the grooves.
The residual groove lettering can be carefully scrapped off with a utility knife blade.
Any discoloration from the scrapping will disappear when the decaling area is gloss coated.
