Posted: Mon Feb 25, 2008 2:39 pm Post subject: Unusual paint ridge around windows

I have had an unusual situation with the  door windows when painting and want to see if anyone else has seen a similar  problem. 

  

 After painting the doors a small ridge  developed above the Plexiglas-fiberglass joint - it is about 1/4 wide and  1/16 high. The area was level and smooth after priming. I used the Weld On 10  and put a thin layer of fiberglass over the seam. I then primed with UV  SmoothPrime and primed over that with the Dupont high build primer. All looked  good until we painted the final color and clear coat (Imron). It seems like some  kind of chemical reaction. 

  

 Anyone else seen this? Any ideas?  Suggestions on how to best fix and avoid this on the other windows?

  

 I have attached a few photos - a little hard  to see the ridge.

  

 Thanks for you input.

John,

  

 The ridge looks like it's  at the edge of the fiberglass.  Is that right, or is the edge of the  fiberglass further from the plex?  What type  of resin did you use to overlay the seam?

Dave,

  

 The ridge is just over  the Weld On seam between the plexi and fiberglass. Its as though the Weld On  expanded when painted over.  I used West System epoxy.

John,



   After you painted the door with Imron, did you bake the paint to help it dry or did you let it air dry?

John,

  

 I think you're right,  there must have been a reaction.  Let's see, Weld-On, base resin,  plexiglass, West System, Smooth Prime, primer, and Imron...quite a few volatile  chemicals all in close proximity.

  

 I would have thought the  overlay would have taken care of that.  I did something similar around the  windsheild of mine, but the overlay went on many months after the bond was  cured.  Maybe that made a difference--allowing the bond to cure  fully.  Also, I used Hysol instead of WeldOn, just because we use it alot,  not because of any other characteristics.

  

 Wish I had something  better to tell you.

I don’t know what caused the ridge, but when I got a crack around one of the windows on a plane I built 20 years ago that followed the contour of the window like your’s does, I took some pinstripe tape from an auto store and overlaid it on the crack/ridge in your case/.  It hid the crack and I didn’t have to repaint.  You might try that and see what you think.

When you guys say you are overlaying glass over the seam, what are you using, what weight of weave, how many laminations? What I am wondering is once you have done this, are you building up the rest of the cabin top to match the contour which this overlay has created, or are you sanding the overlay down so much that it really is much thinner than it was when in full form?

I usually use one layer of about 8 oz and one layer of 4 oz on top of that.  I make it wide enough to cover the joint between the plex and the frame and to extend up on the plex about 1” and back on the frame at least 2”.  Yes you work to make a smooth transition between the glass and the frame with micro and epoxy.  If you want more detailed instructions e-mail me off line.

Dave,  

   

The ridge is just over the Weld On seam between the plexi and fiberglass. Its as though the Weld On expanded when painted over.  I used West System epoxy.

John,  

   

The ridge looks like it's at the edge of the fiberglass.  Is that right, or is the edge of the fiberglass further from the plex?  What type of resin did you use to overlay the seam?

 Subject: Unusual paint ridge around windows    

I have had an unusual situation with the door windows when painting and want to see if anyone else has seen a similar problem.   

    

   

    

After painting the doors a small ridge developed above the Plexiglas-fiberglass joint - it is about 1/4 wide and 1/16 high. The area was level and smooth after priming. I used the Weld On 10 and put a thin layer of fiberglass over the seam. I then primed with UV SmoothPrime and primed over that with the Dupont high build primer. All looked good until we painted the final color and clear coat (Imron). It seems like some kind of chemical reaction.   

    

   

    

Anyone else seen this? Any ideas? Suggestions on how to best fix and avoid this on the other windows?  

    

   

    

I have attached a few photos - a little hard to see the ridge.  

    

   

    

Thanks for you input.

I usually use one layer  of about 8 oz and one layer of 4 oz on top of that.  I make it wide enough  to cover the joint between the plex and the frame and to extend up on the plex  about 1” and back on the frame at least 2”.  Yes you work to make a smooth  transition between the glass and the frame with micro and epoxy.  If you  want more detailed instructions e-mail me off line.

When you guys say you are  overlaying glass over the seam, what are you using, what weight of weave, how  many laminations? What I am wondering is once you have done this, are you  building up the rest of the cabin top to match the contour which this overlay  has created, or are you sanding the overlay down so much that it really is much  thinner than it was when in full form?

John, 

  

I think you're right,  there must have been a reaction.  Let's see, Weld-On, base resin,  plexiglass, West System, Smooth Prime, primer, and Imron...quite a few volatile  chemicals all in close proximity. 

  

I would have thought  the overlay would have taken care of that.  I did something similar around  the windsheild of mine, but the overlay went on many months after the bond  was cured.  Maybe that made a difference--allowing the bond to cure  fully.  Also, I used Hysol instead of WeldOn, just because we use it alot,  not because of any other characteristics. 

  

Wish I had something  better to tell you.

That's pretty light material.  Next time (??) try something like  7781 which is about 8 oz as Gary suggested.  Two layers of that should work  fine and tolerate some pretty significant body work.

   The ridge is just    over the Weld On seam between the plexi and fiberglass. Its as though the Weld    On expanded when painted over.  I used West System epoxy.

   John,

   The ridge looks like    it's at the edge of the fiberglass.  Is that right, or is the edge of the    fiberglass further from the plex?  What    type of resin did you use to overlay the seam?

Subject: Unusual paint ridge    around windows

   I have had an unusual situation with    the door windows when painting and want to see if anyone else has seen a    similar problem. 

   After painting the doors a small ridge    developed above the Plexiglas-fiberglass joint - it is about 1/4 wide and    1/16 high. The area was level and smooth after priming. I used the Weld On 10    and put a thin layer of fiberglass over the seam. I then primed with UV    SmoothPrime and primed over that with the Dupont high build primer. All looked    good until we painted the final color and clear coat (Imron). It seems like    some kind of chemical reaction. 

   Anyone else seen this? Any ideas?    Suggestions on how to best fix and avoid this on the other    windows?

   I have attached a few photos - a little    hard to see the ridge.

   Thanks for you input.
