Ok so I've read just about every "How To" on the Samba I promise. I still have a few unanswered questions. Hopefully I didn't miss something in my reading and I'm not wasting anyone's time.
So let's say you want to preserve OG paint & patina but some of the rust spots are thick and "clumpy" (for lack of a better term). To complicate the matter further let's say some of that clumpy rust is on top of some original graphics in spots.
What would be the best technique to get a smoother finish but maintain the patina, graphics, remaining OG paint etc.... maybe to put a clear coat over. Would a super fine paper do the trick without destroying what you are trying to save?

Are you talking about water/dry sanding the rust down, without sanding through the surrounding paint?
I've never tried it (most times people want the rust GONE) but I think it would be extremely difficult. Rust is pretty hard stuff, usually tackled with grinders and sandblasters. Fine sandpaper won't touch it.
It would be virtually impossible to not damage the surrounding paint while sanding. Compared to rust, paint is pretty thin and it won't take much to make it disappear.
The rust isn't on top of those graphics, it's through the graphics.
Good luck. If you do try it, post up some pics. |

Well most of the rust is just sort of a surface"burned" looking rust. I was just curious if there was a finishing technique that would knock down the cakie looking rust without stripping. There's plenty of rides on this site rocking the rusted look and some have even cleared over it. |

my advise?... don't clear it... use linseed oil to brighten the rust up... at some point the clear will fail, as it's not designed to stick to rust... possibly a clear epoxy will, but I haven't used one yet...
our 56 oval rag top... OG black with perfect patina
I haven't used the linseed oil yet, but I intend to... to be fair, though... we just saw a car that Jer*Fab in Cali built that was cleared-over patina... it's a gorgeous car... just depends on your taste... _________________ 1969 Riviera "Ethel"

Well.....if you want to knock down the cakie rust, I would use a 4 1/2' grinder with a wire wheel. Knock the loose stuff off and if you hit paint and make a ledge use sand paper to blend the area into a smooth transition with the rusty patch. If you go too deep for your liking knocking down the rust, the eliments will bring it back.
