Ok here are a few photos I took.. along with the questions..
1 problem (small)

Ok as you folks know (at least a few of you)..
I need to switch towbars...EU EU and more Eu..ok..
How is the cut made for the ply there where the towbar goes under the entire in front of the trailer? The towbar beam is about 2 inches thick..
Also if you look at the cross bar there of the frame.. underneath just past the styro formation at the radius.. How is the ply fastened to that cross bar...
Would it be ok if I skin just about 6 inches or less above the towbar since I need to cut off the towbar there at the weld unfortunately until I get the new one .. I have to drive to a dealer to have a new towbar fitted so Im just afraid that if I skin all the way down at this moment I may have to tear that skin open again just for the new towbar..(See Below Also) The Fiberglass skin will go on top there as well with a protector shield of Diamond Plate equivalent..about 6 -8 inches high..
Next question is... Will Glue stick to styrofoam? Or Sika Product?
# Should I seal the bottom of the 1st layer of ply with Marine lacquer before laying it on the styro face or is there any point to do so?
I will be gluing the 2nd layer onto the 1st so I know that glue will not stick well if at all if it is varniished before gluing on the next layer...
# Do I need to varnish that ?
Then on top of that I will be gluing on the fiberglass ... (so I was thinking) or can that be floated as aluminum can? Or should I glue that?
I think I got all my questions down now...except for 1 concern..before I glue the 1st layer...
# Ok also I noticed that the sun has dried out the foam pvc on the seams and there are small cracks there...What else can I use to seal them small cracks instead of using the PVC on these areas...??
(3rd photo ) Here I was wondering if I should seal that where the styro and cross beam of the frame meet? and what can I seal it with?
