Before you do anything to it, makle sure you wash it with Dawn or something of that nature. Hell, I wash mine between each round of sanding and such. It's cleaner than our silverware, lol...

Not sure if you've seen my thread in the aresenal, but I've been using the KwikPlastik Epoxy Putty, by JB Weld, found at Home Depot to strengthen and what not...

wanna make sure it never gets fu**ed up ,.......

Giving the bio a light sand isn't going to hurt the bio, if that is your concern. I had the same concerns about the cheek area and even "considered" using epoxy and carbon fiber. Obviously I went with the putty. It's easy to work with and $5 a tube. It's in the spray paint/caulk aisle at Home Depot. After cutting out the eyes, the bio is still quite structurally sound, though I still wouldn't want to drop it on our tile floors, hehehe...

FYI: You are not supposed to use Plumber's Putty on any kind of plastics.

One last tip George gave me, was once you are ready to paint it, spray the inside with PlastiSpray first. It is supposed to minimize the effects from it rubbing on your undermask. As has been stated in other threads, the stuff is "Death In A Can" so do it in a WELL ventilated area. I'll be doing it outside with my respirator on...

You can glass the inside of the bio if you want ..the fiberglass resin will take "as-is" . mold release was sprayed into the mold itself, so the back side should be release free. You should probably know a little about glassing first ..and it would probably be better while its in the mold ,or before the eyes are cut ..if the eyes are cut, you have more of a possibility of the fiberglass resin spilling through that hole and onto the front side of the mask. Also ..if you do glass back it, cut the edges off with a good sharp knife while the glass is still soft ..will save you a huge trimming hassle later. That being said, the two part "clay-like" epoxy putty stick will work just fine to re-enforce those areas. I wouldnt spend too much time with it in the crown area..it will add weight. Glad the bio made it to safe and sound ..and even more that you like it so much ..now on with the build!

That's it?! HA! Try taking off the corner of your finger with a compound miter saw and get back to me, lol...

right on george,.......nah i'm not gonna glass the whole thing,......just the sides that support top to bottom ,.....

probably just a few strips on each side should do me right,.....
i'll just layer it that way it doesn't run all over the place,....
gota wait to sculpt more til i get to work ,....grrrrrr
