maybe just plane old glass laid up with a chopper gun if so it can be very ruff with no cloth marks in glass just hairy .the MSC will be very smooth in side it is press in a mold and it is kicks off with heat all the big semi hoods some gm cars front headders used it and some of the vetts were as well

Why not just give the raw side of the glass a good scratch up and brush a good coat of white gelcoat onto it..It will seal it well,and provide a clean surface..

I try to get some better pics of the fiberglass inside.

The second part of the question is if three step POR 15 or Eastwood system used to the frame inside dripped on the glass would it harm it??.

Read the directions on either product as you do not want to get it on your skin (takes 2.5 months to wear off, ask how I know ). Do not think it will harm the fiberglass. As for curing and a proper finish for the raw glass work, your local Finishmaster will have gelcoat in liquid form, as mentioned above, this is the top coat before you do any paint prep (sanding, priming, painting). Without the gelcoat over your raw fiberglass you do run the risk of moisture working it's way between the layers of fiberglass and resin. This will cause bubbling down the road and eventual failure of the fiberglass matting, so do not skip this important part of the build up.

Thank You Bill.I'll check into that.

Here is two shots of the fiberglass inside.Sure doesn't seem if it is gel-coated.





Photobucket is being a real pain tonight.Got more pics.......but well I guess I got to wait.
