u pol fantastic over lechler epoxy

[squazy84]

hi, ive just downloaded the data sheet from u pol for the fantastic filler as i wish to be sure its safe to use over 2 k epoxy primer by lechler, here is the link to the data sheet
http://www.u-pol.com/documents/datasheets/tds/FANT-TDS-EN.pdf
it says
•
Original paint surfaces
(with the exception of thermoplastic acrylics) – d
egrease and
abrade withP180 grit paper

would 2k epoxy sprayed over bare metal allowed to dry for say a day qualify for the above? thanks for your help

After just a day the epoxy won't be fully cured and some would be happy to apply filler straight on top. I would be tempted to scuff it up a bit or be careful with P180.

Yes fantastic over epoxy is fine but it needs keying with something like 120 grit, don't put it on without keying.

Ok and about the drying time? I've read you should apply it before 7 days after priming

I usually let the epoxy primer dry for 3-4 days but have filled on it after 24 hours without any problems

Thanks for that, I'll give it a few days first

I am just in the process of doing this on my every day car. The epoxy went on on Monday afternoon, 3 coats (because I had plenty of paint in the gun even though I only mixed 85ml). The filler, Upol Fantastic, went on on Tuesday evening and I dry sanded it back last night (Wednesday) before putting a bit more on a couple of spots. Hope I am not rushing it.
