Determining which side goes up when covering with Polyspan
« on: August 19, 2019, 01:16:48 PM »
When covering with Polyspan, it is important to put the right side up.  If you candle it under a light, the shinier side goes up but often times this is hard to determine.  The best way is to drag the Polyspan over a small piece of 600 grit sandpaper.  The down side will want to grab the sandpaper and cause a lot of friction and resistance.  The smooth side, the side you want up, will slide smoothly over the sandpaper.

When you put the wrong side up a dope it, you have a fuzzie problem on your hands that you can rectify, but it takes a lot time and irritates the heck out of you.

Tom told me that 99 times out of 100 it is rolled that way.  Where I run into trouble is when I cut off a piece, get distracted and then come back later and cant remember which side I had up.  At 72 you forget things...
Tom was the one who told me about the sandpaper trick.

Rub it against your face, the fuzzy side, (the side that goes down) will catch on any whiskers you might have.  The shiny side feels much smoother.  Works every time.  You can also feel it on your arm to a lesser degree.

I said rub, but I mean lightly drag it across your face.

If you do get it wrong, after a couple of coats of dope, 2000 grit wet sanded will kill off the fuzz.  H^^

Killing the fuzz after a few coats of dope sure beats trying to get the stuff off.  Profanity was created specifically for doing that.  I have found that the best way to get the right side up is to use silkspan.  However, done right it is pretty good stuff.

I have found that if I hold it up to a light and look down the grain I can see the very slight difference in shine.  I only get about 1 out of 10 wrong using this method.

I found that a light smear of most any glue on my finger.....dried and slowly being peeled off...will drag like beard or the sandpaper...the course/shiny side is very obvious except to old eyes

Does that also work with pretty faces, such as those of the Jive Combat Team?

Not as well.  You have to be a little crude.

JCT members are not that pretty, actually. I know or have met every one of them. Some of the Jivettes may be useful tho. It's been awhile since I've seen a Jivette. I didn't try to rub her with my Polyspan.  ;D Steve
