Re: Peel ply applications

[Steve Nichols <aussieswift@xxxxxxxxxxxx>]

Greg,
   
  At the outset of the project I considered vacuum bagging but decided against 
it due to my inexperience with fibreglassing. Now I have a lot more experience 
but the light at the end of the tunnel in terms of boat completion is getting 
bigger.
   
  Basically I'm too impatient to get into this at this stage of the project!!!
   
  Cheers,

          Steve I presume you have done your deck top. If you are going to use 
peel ply on the underside you might also bag it which eliminates excessive 
resin, any worry about bubbles outgassing and leaves a nice surface to bond 
too.

  Thanks Bram,
   
  I agree, I would like to use the pre wet method on the hull but would make 
sure i had at least 2 and preferably 3 people around to manouvre the rollers, 
cloth and resin.
  I'll keep using it on jobs as large as the wings alone as it does give better 
results.

  Steve,
   
  Thanks for the good info.  
   
  It is true that the s-glass 8 plait satin weave we use is hard to wet out 
from the top.  The trouble is that when resin is applied on top of the cloth it 
tends to seal the weave and trap air beneath.  In a perfect world we would 
always wet out the part and set the cloth on the wet out surface.  That way you 
squeegee the resin into the cloth from the bottom  and chase the air out.  I 
use this method on all small parts.
   
  On large surfaces when working alone, it is often impractical to wet out the 
part before applying the cloth.  When you are forced to apply the resin on top 
of the cloth because of time considerations, I've found that, once you have a 
small wet out area,you should always dump the new resin on top of the wet out 
surface and squeegee it onto the dry cloth surface with some pressure.  This 
process helps minimize the amount of trapped air a bit.
   
  Thanks again for the input Steve.
   
  Best regards,
   
  Bram
