Seal and peel would be the solution to your curing time problem. It’s a thermoplastic hot melt which air cures as quick as 30 seconds. http://www.interfluxusa.com/Datasheets-PDF/Seal-and-Peel-(DSRev08).pdf

I would suggest lowering the viscosity even more. Humiseal even sells 1B31 pre-mixed specifically for spray machines and the highest they go is 65cps.

Seen it. We use a lead free process, sometimes our supplier will use a lead process silk screen that burns at a lower temp. The HASL coat was still SN100CL.

Thanks for the replies. It looks like the fuse clip itself is the problem, it seems the "coating" is a chrome like finish over a copper, I believe, anyway I hit the legs with some Emory cloth and inserted them in the board and they were fine after r
