I don't think I have ever seen the old FAs-Cal in person!! Or knew where to get that. I don't know what SLC is but I guess it's similar?? Is your source north of the boarder on this side?? I was going through my covering stash the other day and found some polls of clear material that has no label and I know it's not clear Monokote. I think I have a small roll of Doculam that I bought off eBay but I didn't mark it.
   Does the stuff you bought have a sticky side? or attach it with some so rt of adhesive?? I just may have to acquire a roll. Will probably be more than I'll ever use.
  Type at you later,

SLC is/was biaxially oriented polyester film with a low temp adhesive.  The origins of it are from the lidding industry for food, I believe.  Unless you own a yogurt or margarine or frozen food packaging factory, small quantities really aren't readily available other than from Phil.

99 cents a foot? Shame on him. Buy it on Amazon for 8.9 cents a foot in the link above Ken.

I saw those.  That was the only one I could find that sold it in the length I needed.  I have yet to thoroughly test it so why invest in 200' when 190' of that will sit on a shelf if I decide the experiment was a flop?

Here you go. Now everyone can have a roll. Its called LAMINATING FILM, Not 'SLC'

Using lamination film is no secret.  50 years of folks using the endless varieties of cheap clear films, especially in combat. 
SLC was the name Phil gave the variety he sold.  Super Light Covering.  And it was lightweight.  The original variety he sold for 15-20 years was .75mil. It was a different product than lamination film for the printing industry.  The adhesive is different and the feel of the film is different.  I literally have miles of various types and brands of low temp 1.2mil-1.7mil film from the printing/photo lamination industry.  I'm not arguing with you, just illustrating that SLC was a unique product, sourced from a different channel. 
All of the various low temp films seem to work pretty well for how we use them.

All that info is great, but useless if you cant provide a source of where to get it.

I am not sure what that means.  I quoted my source, the RC sites.  I also posed the question of your specific brand to the Bing AI and it's research said it was not suited for foam.  I also read all of the negative reviews for the product listing and quite a few of the positive.  All had one common theme, it doesn't stick without excessive heat.  I assume that was outside of the laminating press for which it is designed.  One of them was particularly enlightening - the roll came with the 1st foot wrinkled and not in factory packaging.  They said that the add said that packaging may not be standard.  Simply put they bought a return and they must have a lot of them to put that in the listing.  I couldn't find that in the listing but that might have been removed after the review.  Another red flag was that on the 500' roll they would only allow you to view the 5 star reviews.  31% were negative.

My point is similar to yours.  You want to save money which is fine.
Mine is to trust the findings of the experts in our community, and I include RC in that.

I appologize for not explaining my search criteria in my original post, it might have saved all of this but there was one other.  I am using Mod Podge to avoid getting kicked out of the building for stinking it up. Mod Podge will bubble up if you use too much heat.  Even MonoKote has to be put on gently. Duculam adhered perfectly at a temperature that would barely stick MonoKote and zero bubbles.
