I recently purchased some awesome Dewalt quick grip type clamps,
The problem is the black metal that the spine of the clamp is made of, when in contact with glue sends the glue black and stains the timber during the glue up, Please see attached a pic of a recent glue up that had the problem.
Anybody experienced this? Or have a solution?
Thanks in advance.

I have this happen with black pipe clamps all the time. Oak is particularly bad. It's generally not a problem if you are hand tool woodworking because you wind up planing it off. If there is no further finishing work to be done after glue-up, then put some painters tape on the bar so it doesn't contact the glue. No contact = no chemical reaction.

Thanks to everybody for the comments, I am happy its not just me who has the problem.
Seems I will need to tape these things, as I said in the beginning , extremely good strong and versatile clamps.
Just the blackening is painful.

And thats a yes from me.
If you have a Look at MTMWood on you tube he uses PVC conduit on his clamps.


In fact maybe you shouldnt look as you will be wanting to make some impressive cutting boards next !!

I found an interesting idea in a YouTube comment for using black pipe in your clamps. Cut a thin grove in a PVC pipe and then cut it into 2 to 3 in lengths. You can snap those little pieces over the black pipe as you need them and slide them into place at the glue joints. It has worked out quite well for me. I have a drawer full of these now and use them in large glue ups.
