Flexible filler recommendations

[waddycall]

Hi,
Can anyone recommend a decent flexible body filler for aluminium that’s good for repairs about 12mm deep and idiot proof?
Thanks

UPOL do some, and I've used the Big Boy Metal Filler as well.
But 12mm is a lot, double the maximum you would really want to have - so high chance of cracking.
Can you not get the panel much closer the finished size.

Plastic padding Alu, what used to be Ultima. Used it in mold making and know it can take a bashing without letting go, you can get a dispenser for it that makes sure the correct filler/hardener ratio gets mixed

I had too fill a bit of a depression on my hot rod roof as i had a poor match of panels and went with the P40 with fibreglass, been on for a good few years with no issue

Hello, is U-Pol Fantastic body filler the filler of choice? Are there better alternatives?

Most body fillers are now good for most properly prepped substrates now. I prefer Fantastic for ease of use. However. 12mm is a big ask. It will, in time crack.

This is for my Citroen DS, 3mm maximum.
I shall get some more Fantastic.
Thanks

I vote for Upol. I’ve used it in several cars, the stuff is bulletproof.
