my first fiberglass box build

[IbSlamn 10+ year member]

man!! talk about lots of sanding. i went through like 5 sheets of sand paper and sanded for like an hour and i still have a good bit to sand..i will get pics up in a lil. but for this being my first fg box i think i have done pretty good. i see lots of high and low spots but i will get the body filler on that. but my question is do i just use plain body filler and put on the whole thing or do i mix stuff??

its kinda dark but this is after the first sanding of the fg. still have to do a little more then put body filler on it. for my first time i think i did alright. what do yall think?

If you're going to paint it then sanding is very very important.

if u read down, he goes on to mix body filler and resin, and it paints on much better i guess.

Good job, man!

I plan on making some stuff out of FG soon.

That 4 parts MDF 1 part fiberglass seems pretty simple.

Looks real good. I used body filler on my door panels. Some of the "pros" use gel coat.

That's such a freaking waste it's unbelievable. Why on earth would you take just about the easiest sanding filler on the market and add resin to make it more difficult to sand? That's just farking stupid. If you have deep (1/4" or deeper) low spots to fill. Slap on some kitty hair( fiberglass reinforced filler) sand , then just use straight body filler on top without adding anything. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

from what i understand it makes it more of a liquid by adding the resin so you actually have less sanding to do. it fills in the low spots a lot faster than laying kitty hair. we generally just use rage gold or a similar body filler and start sanding when it is about 3/4 of the way dry. in my opinion, that's easier.
