first time doing a how to so bear with me.
First you have to figure out where and how you want to mount your gauge, then make sure that you can run your wiring and get those little a$$ nuts on the back of the stupid thing once you get the pod done.
I chose the drivers side inside mirror panel.
Materials:
gauge....duh
gauge cup. if you cant find them i will cover how to make them later
masking tape
spot putty
body filler
fiber glass resin and MEKP hardener
fiber glass mat
sand paper.... 100+250 dry,400+800 wet will do fine
card board
junk playing card
utility knife
cheap brush approx 2" wide
mixing cup
putty knife or similar tool to mix and spread body filler
dremel rotary tool is a life saver
palm sander, also a life saver
water spray bottle
neoprene gloves
safety glasses
respirator
can of primer
now im gonna play shop teacher for a second, remember just like in high school..... SAFETY FIRST always wear glasses, respirator and gloves when sanding or working with filler/ glass, the fumes and dust can really mess you up.
there, now that thats out of the way...........
step 1:
put the gauge in the gauge cup and position it how you want, then tape it down so it wont move. NOTE. you may have to cut a hole in the piece your using for a base.
step 2:
mix a small amount of body filler and spread it in aroung where the cup meets the base piece like so..
let the filler dry and remove tape.
step 3:
put back in vehicle and check positioning/ fitment
step 4:
fill around the cup to begin adding shape and support
step 5:
make sure gauge still sits properly in cup. then remove
at this point it should look something like this
step 6:
cut 2 triangles out of the fiberglass mat large enough to over lap the edges of the hole by 3/4 of an inch and come at least 3/4 of the way up the cup.
step 7:
now mix a small amount of resin and brush onto the pod where you are going to be laying fiber glass.
step 8:
carefully lay one of the pieces you cut over the hole and press down all the edges, while holding the mat on to the cup brush resin into the rest of the mat. alternatively you can dip the mat in the resin and then position it how you want it. while the first piece is still wet, put your second piece directly over top of it and brush the resin in or dip it and stick it. MAKE SURE YOU GET ALL THE AIR BUBBLES OUT.
after about 3 hours dry time it should look like this
step 9:
sand off any sharp edges and high areas
step 10:
check fitment of both pod and gauge and remove
step 11:
mix up some body filler and spread it over the pod, try not to make it to thick or thin in any particular area, and try to keep it as smooth as possible, it means less work later
after that dries it should look like this
step 12:
sand the filler down so that its smooth, if you find any deep lines or holes, blow the piece off and fill them, then sand again
step 13:
at this point there shouldnt be any big pits or deformity's in your pod and it should have a nice shape to it, to fill all the little pits, use a junk playing card and some spot putty/ glaze. squeeze about a tooth paste amount out onto a piece of cardboard and with the playing card press the putty into the pit and scape the excess off, leaving just a thin film across the surface. allow approw 1.5 hrs for dry and cure time
step 14:
take the water spray bottle and fill with shower temp water. now go out side and spray the pod and the 400 wet/dry paper. now sand the pod until all the tiny bumps and ripples are gone. dont forget to spray the paper and pod clean every once in a while.... while sanding, this keeps the paper from clogging up. at this point the surface should be smooth and ready for paint if not, use the spot putty to fill and repeat.
at this point the pod should look like this
step 15:
now your ready to prime. let the piece dry for at least 3 hours to get all the moisture out then hang from a wire and spray it with a medium coat of primer after 20 mins, add another medium coat. then let dry for 3-4 hours
step 16:
same as step 14 but use the 800 wet and sand the primer till its smooth as glass
at this point it should look like this
step 17:
let dry for 2-3 hours then paint with what ever you want. for better results wet sand the paint with 2000 and use a polishing compound to make it shine. then clear coat it if you want and your done.
well that should be it. if i forgot anything feel free to add.
many changes in the making
