I have tree sap all over my enclosed trailer and I can not find a way to get it off. Last time we used the trailer was about 3 years ago (that's about how long ago we parked the race car) and it has set beside my house with a line of trees on one side off it. I was off work today and it was nice outside so I thought I would try to clean it up. I didn't realize how bad the sap was. I wish I would have done something about this before now.
I tried a ton of tar/sap removers and I read on line that Diesel Fuel would take it off but, it didn't even phase it. Any ideas on what would get this stuff off ?
I will post pics so you can see how bad it is
