I finished gilding some stripes and graphics on a frshly painted Harley last week. They need to go back to the paint shop for clearing. I gilded over 3 coats of HOK clear and now 3 more coats are to be applied. What should I do before bringing them back to the painter? I sure don't want him using any kind of cleaning solvent on my work before he shoots them, so how do I protect it?

If it were me I would take the tank to the painter and stand over him while he preps it. That way you can be sure he won't do any damage to the gold. You don't have to actually be inside the booth when the spraying takes place though.
Personally, since I have the equipment, I would spray one coat of HOK clear before releasing the tank for final coats.

Did you wet sand the first "generation" of clear, prior to guilding?
What we do here, with HOK or PPG clears, is give the job a coat or two of clear, wet sand it with 1000, and do our guilding and or striping. then, after giving it all sufficient drying time (usually a couple days, if not three, and reclear. By sanding PRIOR to gilding, I have to just tack the job, not sand it, handle it a lot, or worse yet, reclean it with solvent.
If you DO need to rewipe with solvent, use something fast-evaporating (like PPG DT320), and avoid making direct contact with the gild.
On a related note, after using the same size for 15 years...I switched to 1Shot's size last year, and it's great for automotive clearing applications.
Hope SOMETHING here helps,
keep on keepin' on

After making sure I have the gild complete with absolutly no pinholes,I brush clear over the gold with a single stage automotive clear with hardener mix without any thinner added. This should create a barrier between the gild and any harsh solvents that might blister the size thru the gold, when the stronger clear is sprayed. I have only had bad reactions when harsh solvents used in automotive clears are sprayed directly on the gold. When 99 out of 100 automotive painters spray they mix quite a bit of the harsher solvents with the clear as it is usually the correct formula for spraying. It is this extra amount of solvent that causes 99 out of 100 problems with underlying paint that is not compatible with these clear coats,..in this circumstance the size used for the gold.
