My Pyro has a patch, installed by the dealer from whom it was purchased, that has lifted/delaminated just enough at one edge that it’s leaking.
I don’t want to pull all of the patch off as the majority of it is firmly adhered. Can I apply a OR patch on top of an existing patch - will the smooth coated side of the new patch bond well to the fabric side of the existing patch ? Will it leak at the edge or step between the suit and the old patch ?
Also, my heat gun has temperature control - what is the recommended hot air temperature for bonding a patch, or the melting temperature of the coating on the patch or suit ?
Thanks in advance for help on this one !
I hope this reply is too late, and you’re already out ripping dry and comfy in your Pyro. Yesterday I experienced this typical pinpoint cold spot every time I went splash, and I found an old patch lifted up at one side - just like you describe.
I used a paint stripper in setting I (of II), and went at the whitish side of the patch until it turned liquid, you can see a sudden change in texture and shininess. At that point you can just press the patch back and hold it a little.
I think it’s basically a film of hot melt adhesive that turns out to be reusable - if it’s not heated enough the 1st time around.
