I hope this it the proper forum for this.
I stripped paint off an MTH hopper car using 91% Isopropyl alcohol.
After a 24 hour bath, I had fantastic results with everything except the car ends. I soaked them for 48 hours and this is as clean as they will come.
Is this good enough for primer or do I really need to get rid of that residual yellow paint? I'm painting the car black.
Thanks for your thoughts.
