i think so too, i have some body damage profesionally done on my wheel arch 4 years ago and no rust blisters it was repaired very soon after the damage so should be ok
Right, im confused. I'm only 15 and already have my first car. I've got a 1969 Ford Escort Mk1. I'm currently restoring it as a project before I go into bodywork and spraying. I'm about to use filler on a front panel that was badly dented. Do i have to use metal filler first seeing as ive sanded the car back down to bare metal then use poly-filler? The panel has tiny holes the size of a pin head - Do these have to be filled in before using filler over it? And what filler do you recommend? Thanks
Body filler on bare metal caused that rust! i don't think so! if you apply body filler over rust holes, poor welding or any hole no matter how small then yes it will rust but not clean straight metal.
we always apply the filler on bare metal but when the part is sanded smooth we put washprimer over it to prevent any rust problems in the future
Thats a funny username you have..(made me giggle)
yup, If not the filler saping moisture, it could be dirt building up on the inside of the panel.
yeah, phobiablack...what you say makes sense, but it would have to be a repair that didn't get sealed with epoxy (or urethane?) primer and then sat in the weather. the car in the video was painted. i suppose it could've been exposed to weather before it was painted, but they don't say. i made a habit of putting filler over self-etching primer, then always priming over a repair right after sanding it. so far so good.
Filler works over bare metal just fine, BUT If you apply filler you need to seal it off from absorbing water with epoxy primer. Some people even apply filler over epoxy, I havent tried it personally.
im in the same situation, im about to cut away the rusted panel of my datsun 510, then i guess apply body filler over the bare metal??? im guessing it would be a good idea to prime the area after welding/grinding the new panel i created
What after applying the Filler?
correct
thanks a lot.
Body work is something you have to try to understand, doing research on the net makes me less and less worried about doing some of it myself when I get the '65 'Pala
Body filler can go over both metal and paint. If over paint then the body filler will only hold as good as the paints hold on the car.If the filler is painted and sealed correctly then no rust will happen. In the vid the spot they are looking at has rusted from the other side of the panel. Most likley a nice cosmetic job was done on the outside but the inside of the guard was not protected properly causing this rust
My thoughts exactly, so wtf am I supposed to do then?

he says not to put filler on bare metal, then in another segment, after they've welded and smoothed the metal, they apply filler directly to the metal. am i missing something here?
