Plexiglass protection during construction
Is there a spray on plexiglass protector available and if so, where can it be sourced?

Comes in gallon cans. I got mine from General Chemical Corp. $48.25/gal, but the shipping was about $24 for US delivery. A gallon is plenty!

I used half of the quart bottle from ACS for my RV-4 canopy, inside and outside, petty thick layers.
I would think that a quart would be enough for an RV-7.

SPRAYLAT SIGN STRIP
Several makers of this stuff; the age-old sign version for spraying plexi signs is now owned by PPG, still called Spraylat. Not a lot cheaper than the products mentioned here.
NOTE: do NOT let this stuff 'dry out' in direct sunlight or a hot shop. If somehow it ends up on there for years, it will be very hard to remove.
I don't think there is such a thing as 'too thick'. It makes it much easier to peel.
If yours ages and becomes brittle, roll on another coat; this will moisten the old layer, and give you more to hang onto when peeling.
happy canopy'ing!

Discoat 4220 Question
Does this material resist both Acetone and West 105 ?. Sounds like useful stuff, I just want to understand any limitations, thanks.

Just bought disccoat 4220... haven't applied it yet as I'm preparing for my daughter's wedding. Weighing spraying vs. brushing on. I'm looking forward to more posts on this.

Shelf Life
Keep in mind the his stuff has a shelf life and goes bad in time.
I bought it when I was building and never used it. Sold it to Vic Syracuse on here and when he received notified me it had gone bad. Was no longer usable at all!
