Rod,

I used Fusion plastic paint that I bought at Canadian Tire to paint the backside of the of the windows.

I also used the 4991 tape - my understanding was that the thicker tape increased the thickness of the silicone layer and that allows it to absorb more movement -- plus the tape can absorb the movement as will with the thicker foam layer.

I believe my tape was 1/2" wide.  I'll try to get a rough measurement of what I have for extra.

I was not too successful trying to polish the edges of my plexi -- but found a quick pass with a torch worked pretty well.

I used my finger to smooth the silicone - years of painting houses to pay for school it was a pretty familiar technique for me.

So do we have some agreement:

 

  1. Best material for windows Plexiglass of similar product
  2. Best application 3M VHB 5952 tape
  3. Best sealant Dow Corning 795 or Pecora 895  (same properties)
  4. Paint behind windows black or coloring the area behind the window (cavity) that is not taped to improve the appearance. ??? I believe I read somewhere black paint will work fine but will someone who has done it please confirm?
  5. Once windows are taped in place mask well and force sealant into edge of window.
  6. Smooth sealant with a plastic spoon or some other device to create a smooth finish
  7. Allow to cure a bit prior to removing masking tape so that the sealant peels off better.

I figure 1 tube per side. All depends on gap and application technique.

Last question:  will one tube of caulking do four windows?

This might be why 3M recommends the 5952:

 

·        Creates a permanent seal against water, moisture and more by offering better gap filling capabilities

That's in the 5952 description on the 3M site.  It does not appear in the 4941 description.  Could be the 5952 is more closed cell foam than the 4941.

Incidentally, I noted in a previous e-mail that a 3M rep I talked to (by calling in) recommended 5952 over 4941.  I just inquired again – this time by e-mail.  3M responded that that it recommends the 59XX series for this application.  For what it’s worth.
