Hello fellow model makers,
I am in the process of machining some OBO Modulan 302 to be used as a vacuum buck. In the past I have used Nason 2K High build Primer Sealer, to seal the surface but haven't been thrilled with the results. I have had instances of it heating up and sagging, getting stuck to the formed part and ripping chunks out of the form, and it goes on fairly thick, ultimately changing the dimensions of the part.
So does anyone have a suggestion for a product that can seal the surface os 20 Lb foam without adding too much build up, and that will stay adhered to the surface of the mold at temps needed for vac forming?
I seem to remember a great wipe on product that I used during an internship in college, but that was over a decade ago and I can't recall it now for the life of me.
Any tips are welcome!
Thanks,
Jake |
