Also helps to use primer as guide to stop sanding when it shows through. A lot of people keep sanding when bare metal high spots appear and just helps to defeat the purpose. Nice Caddy, BTW.

Problem I've had using epoxy before filler is I almost always sand through it to bare metal in a few spots after I've applied the filler. I usually do another light coat of epoxy primer before moving on then. I dunno if that's the right way to do it. I've also used epoxy filler on bare metal instead of primer. But I don't think they are equivalent at all, but better than polyester based filler I think?

Are you applying the body filler before or after the epoxy primer cures? Does it make a difference either way?

Has to be within the recoat window of the epoxy without sanding. Once the epoxy is fully cured the filler wont have good adhesion.

Block the body filler with 80 till you get it really close then do a skim coat of polyester putty and block that with 120 and your ready to prime.

Strange that water in body filler is bad but you can spray a water based primer directly over bare metal. Do you spot prime cut throughs with the VP2050 before applying another coat of filler? No one seems to want to answer this question. Thanks
@jakeymon222 жыл бұрын
if you break through to bare metal, yes. the key is to not cut through to bare metal at this point. block add filler to lows and when you have everything to one level step to your final grit this when if you cut through to bare its ok because you will be applying another application of primer preferably a high build epoxy.
@class5bodyworks2 жыл бұрын
@@jakeymon22 Thanks for the response. I know there is so much emphasis on not putting filler over metal so it just seems very time consuming when you do cut through to have to spot prime, let cure and fill again. I use VP2050 and it's a relatively slow drying primer. I've also seen the shrink test here about allowing three days to dry. To do filler on this scale and not cut through youd have to start with extremely flat panels or possibly get all this filler straight in one coat. Seems like a pretty tall order. Not saying it can't be done, just wondering how many cut throughs are directly filled or get a second round of primer and maybe that's why no one wants to answer the question. Maybe "cheating" a little?

@SealofPerfection9 ай бұрын
It might be a hybrid, but it's not a true epoxy. True epoxy seals the metal, 2050 does not. The TDS states you can apply a PPG sealer over it if you like. An epoxy wouldn't need a sealer. And nowhere in their paperwork does PPG claim it's epoxy. So I'm very skeptical that it is.

@@SealofPerfectionCorrect. I spoke with a rep at PPG. It’s an epoxy/polyester blend. I applied it over a steel plate and left it out in the elements for a year. Within 6 months rust started creeping through. This does not happen with a purebred epoxy.
@SealofPerfection6 ай бұрын
@@LynchAutoHouse Yeah, the TDS even says "If preferred, VP2050 may be directly topcoated or sealed with a compatible PPG sealer." So it's not a sealer, otherwise why would the say you could seal it? There'd be no need if the 2050 itself was an actual sealer. And nowhere in the TDS is the word "epoxy".

I thought epoxy sealers can’t be sanded? That’s what makes all this stuff so confusing, if you put filler over epoxy primer/sealer and fillers get sanded then that means the surrounding epoxy gets sanded too. I’m so confused by this.

@@hserieshooligan1997 Some epoxies are different so I would recommend you check the data sheet. For most epoxies including PPG 408- Epotec I would leave it for a couple of days to make sure it’s fully cured and not going to sink or shrink, then filler on top. Putting filler straight onto fresh epoxy might cause adhesion issues with two dissimilar materials curing at different rates.
