    Ramos! Let's Talk Bondo!

    Ok, u seem to know a lot about bondo.

    I bought some Bondo Body Filler, from Bondo the company.

    The instructions are.....sketchy to me.

    They say for every 3 in diameter circle, 1/2 in thick of filler i should use 3 in stip of hardener?

    Does this sound right?

    Reason i ask is, it's a lot of filler for such a small amount of hardner.

    And on a side note, just want to make sure.

    -Bondo the imperfections
    -Sand while hardening (Grit A)
    -Primer
    -Sand (Grit B)
    -Paint

    For Grit A and B, what do you recommend?

    Thanks a lot man U ROCK!

    Nah, it's all the fiberglass and body filler fumes I have absorbed over the years that sank in


    It sounds about right to me . But I myself would do a little expiramenting with small amounts of each to get the mixture right for your current weather. If it's cold ( below 60 ) you might need to mix it a little hotter ( more mekp ) warmer a little less. Too hot though will make the bondo brittle when it dries.

    For A the roughest you can find. The absolute best thing to use is a cheese grater style body file. What your doing here is getting rid of all of the ridges and high spots in the filler.

    B will need to come before the primer.
    B I would step down progressivly from 120 to 400 or 500 grit.

    Anything else let me know

    You may also want to apply a small skim coat after sanding if there are any pin holes. A few layers of primer and some blocking should take care of any imperfections or sand scratches after that.

    Personally, I would finish sanding my bondo after the 400 grit and then do 400 and then 600 blocking (possibly even wet depending on the finish you are looking for).

    Thanks a lot guys.

    What did you use to mix and apply it?

    Was thinking wooden splint sticks.

    Look around at a body supply shop. They have spreaders of different sizes that are used for that.

    Re: Ramos! Let's Talk Bondo!

    Usually you would use a rubber spactula or spreader (?). But DEFINATElY sand while it's like hard play-doh. That way the ridges and everything are taken care of. If you have a big surface, hell even a small one, a D/A or Orbital sander does wonders. I sanded my bondo down with something like 30 grit or so. I can't remember what it was I just asked for the grittiest **** I could find.

    Hope this helps...
