    need some fiberglass help on wrapping my tablet install.

    I am almost to the point of wrapping and glassing the outside of my tablet install. I still need to get the volume and tuning knobs in place (bottom left and right side). I want to use a thinner fabric to wrap it because I do not want to add a lot of thickness to the edge since this fits in a cutout in my car. I can later add fiberglass from the inside to keep it strong.
    My question is what is the best way to make sure I get a good bond to all the black plastic pieces. Should I use a spray adhesive so the fabric sticks to all the parts and apply resin over top? Also for the two knobs I need to keep that circle area clean otherwise I will not be able to get them back on, should I just use blue tape?

    Any other tips or suggestions would be greatly appreciated thanks!

    if your black plastics , are ABS , or PB (Which probably are) , then i think that fiberglass bonds pretty well with it just with rasin. cutting some deep scars in the plastic, will also make the bond stronger...
    i personally dont even use fiber glass to bond plastics. i just use sterine based plastic puty (used in body shops for bumpers) (BUT fiberglass bonds way better) . but you can easily make a test to be sure. cut a piece of plastic, and apply some fiberglass cloth and raisin atop of it. let it dry, and then see how it bonds...

    as for the circles. cut toilet paper rolls, and make them smaller to fir the holes, (use aluminum foil to stick the paper rolls). the reason for this, is that, the fiberglass will glue everywhere it is applied, no matter what. so when tis dried, you have to be able to cut the fiberglass, from wherever you dont want it..

    Appreciate the reply but im not 100% clear on the toilet paper technique, do I leave the knobs on or remove them before putting the paper rolls on? Also is the foil just used to close the center of the roll?

    If you slice a toilet roll down the center long wise you can change the size of the roll to fit into the pieces you want to protect. Make sure to tape the roll and also make sure you coat the roll well because the paper will absorb the fiberglass making it very hard to remove later.

    Also, you can use any material with fiberglass. You do not HAVE to use fiberglass material. There are MANY youtube videos on using Fiberglass. Just make sure that you check the material of choice that it is compatible with the fiberglass because it can melt incompatible materials. we used a speaker material that had a lot of give to it in a build I did 15 years ago. It worked really well but I don't recall what the material actually was. We stapled the cloth in place. If you glue it into place you will want to make sure the glue is fiberglass compatible because the fiberglass could just melt the glue. We used loose fiberglass strands to build up the speaker grill material.

    exactly. the knobs have to be removed. place the toilet paper, in the same way that you would , with the knobs!!

    the fabric can be any nylon-based fabric. like bed sheets, (The ones that can be stretched easy)

    Scar the plastic and drill holes into the plastic. This way when you add mat and resin, the resin soaks the material and goes through the holes. This will make the resin act like a rivet,.. it doesn't matter what surface it bonds to this way... it'll never separate. You can use nylon material to stretch and bond it accurately with crazy glue. It doesn't except resin well at all so just wet it a little and let dry (it'll always be soft until you put f mat on the back.

    Tape off the dash at least 5 to 6 inches past the edge of the bezel. install the bezel. Skim coat the entire front surface with fiberglass resin jelly and overlap the edge onto the taped dash. Once hard, removed and sand smooth. Overlap the edge so that you can sand it down and you're edge gap will be uniform the whole way round making it look laser cut.
