If I say I have a 59 4 x 4 then they assume its an old truck on a Blazer frame.
Exactly.
I don't think the soap or grease will work when it is bolt head on paint, just too much friction and twisting. I think a washer with grease/soap is the only way to keep it from chipping. If that doesn't work, there may have been a problem at the painting stage. And that is where my experience is lacking.
My truck is almost done! After 6 years! The rear fenders, steps, rear sill and hood are the last items to be painted. Hopefully, it will be on the road in a month. I just wound up the cable for the winch, sooo awesome. Here is the latest picture.
My baby.
