View Full Version : fiberglass sub box ?

if i lay down trashbags instead of putting down a crap load of painters tape, would the fiberglass (when it drys) come off of the trashbags?

it might, if it doesnt eat through it

i wouldnt do it

resin will probably eat it. Painter's tape & layer of tin foil is the way I do it.

aight sounds good then, tinfoil it is.

Yes, tinfoil is the way to go for easy uninstallation.

masking tape + vaseline worked really well for me today.

just FYI - ive tried it, and its a pain in the ***.

basically - the bags will only stick to where you tape them down, and thatis on the edges. so when you lay the glass, the whole middle part shifts and moves and is all gay, then you get an uneven rear part that is all wrinkly... so when you go to put your next layer down, its all ****** and full of bubbles.

tape + foil + PAM spray works quite well. get the 2" wide tape on the interweb, and you will be very happy.

I like to use Painters tape / tin foil / vaseline. I have also tried the trash bag thing and the resin eventually eats through it and makes it really bubbly.

sure will do, i got almost all of the taping done and tinfoil. the first base could be down wednesday, just depends on how busy i am. then thursday my highschool's girls bball team made it to state so depending on how far they make will depend on how much i'll get done.

here it is in the jeep and then after the second layer of mat. how many layers do u guys think it'll take?

Looks good.

I usually just use duct tape. Resin doesn't stick to it.

It looks good... but your probably better off with 3/4 MDF on those flat parts...

Yeah use MDF WHEREVER, you can. IF ITS BIGGER THEN ABOUT 1'x1' use MDF, itll be WAY stronger, and you will save HUGE amounts on ****en mat, which is exspensive as fawk.
