Hi all, I am newbie as they say, I have a question, I have read that carvers use a guide coat to highlight the scratches in their carving while smoothing. I have been using some light grey rustolium( I just happen to have some) So my question is, what do you use that has a thinner body? with the rustolium that I use ,I spend just as much time removing the paint as removing the scratches.
thank you
David

why not just use a sharpie? as long as the stone does not soak up ink deep inside....
Bettter yet, just use a magnafier and watch for the scratches to disappear, then move on. It's what our granite guys do.

I use the sharpie to draw what I am going to carve, never thought of using it as a guide coat,
thank you

why not just use a sharpie? as long as the stone does not soak up ink deep inside.... Very important point about having a non-porous stone. If the sharpie ink gets in there, just toss it. Trust me. I even ruined a nice rose quartz cab this way because the ink got pulled in where the crystal faces meet. I was thinking of trying a china marker instead but I keep forgetting to pick one up. No ink that way and it should resist the water and not rinse off. |

Yup. I use a guide coat when polishing but only if I know that the stone won't absorb the ink. maybe a grease pencil would work better.

So far I have only carved nephrite Jade and some blue Lawsonite and the sharpie does not penetrate it when I have used it for sketching the carving. but you are right soft porous stones would be easily ruined. I will look into other spray paints and let you know what I come up with.
thanks all

Sharpie makes a silver colored pen. It is more of a paint and less of an "ink". I doubt it would soak in.
Is your lawsonite blue in person? I have found it's only blue in pictures, but never in person.

I don't carve, but on my cabs I use an Al scribe & a cross-hatch pattern to guid my grinding & sanding. It definately will not be absorbed, but would probably be a "pain" to apply to a carving.

yes the lawsonite is blue. I saw on an old thread that Kris from "Rockhound field trip fanatics" had offered some to be carved. how did that end up? I don't remember where I saw it. and on the (I am assuming you mean aluminum?) probably would not work on what I am doing. I will post some pictures in the future.

I have 30 pounds and have seen a hundred more. None of what I have seen is blue. Only is photoshopped images have I seen it be blue.

Hi all, if anyone is still curious? I tried a rattle can of automotive grade "guide coat" and it worked well for highlighting scratches when smoothing carvings.

Yes, interested. Where would I get it? Automotive store? Home Depot? Name? Thanks.

Pat, yes an automotive store like NAPA would have it. you can get black and a white for darker stones. clean your stone in alcohol or acetone before you spray a lite coating, then smooth as you normally would, the contrasting color will highlight the scratches, when all of the guide coat is gone, so are the scratches.

Roy, so you do auto body repair and paint work too, I thought I was the only one. I was a tech for 28 years, taught at Wyotech for 71/2 years and now am a trainer for cooks Collision in Sacramento.
I would now rather be Rockhounding or carving!

I used to do paint and body work, too. I used the guidecoat, too, but never thought of it for stones. Should work great. I might have to give that a try.

That is not how it's done, godloveme88. Believe me, you aren't the first to try. Keep it up, you may get banned.
Do it the right way, become a true member of the forum, post, share.
Agree with krazydiamond. While not a "risk" for an RTHling to sell to an unknown person, I think that person needs to earn the right to do any of those three things. In recent times, too many people are just jumping in to take advantage of the generosity of forum members and receive great deals. That should be reserved for family members.
Ya gotta earn it, honey. Jean

I'm with Phil on this one. I use aluminum tig rod or brass wire and scratch a criss cross over the area I'm working. Probably won't work in some concave features of carvings though.
