Sorry steve but I think that sounds a bit misleadings, to anyone who does not understand, jotun epoxy is actually much tougher and it keeps rust away longer than the lechler epoxy, hence why jotun is used on ships,bridges,etc.. don't get me wrong, i think both of these epoxies are as good as...
As Richie says epoxy is all you will need. I have actually used hydrate 80 a lot when it first came out and I never seemed to have any luck with it, in my experience it caused some paint adhesion problems, rust bubbles up again underneath it most of the time, as it only converts the top layer of...
We all know that filling isn't the right way to do it, but I get the feeling he wants to do a quick fix(bodge) and that's up to him if he wants to do that.
If your just going to fill the holes, I would brush on the epoxy primer first(which I think will probably fill the holes) and any holes that are still there you can fill with a bit of fibreglass over the epoxy.
Get yourself a twist knot wire wheel(http://www.ebay.co.uk/itm/NEW-4-100mm-Twist-Knot-Wire-Wheel-Rust-Removal-Weld-Prep-DIY-Brush-11000RPM-/171483642432?hash=item27ed38ba40:g:bLgAAOxypeRR6T97) on a angle grinder and remove the worst of the rust, then get some jotun 87 aluminium 2k primer and...
Got one of these about 5 years ago, was about £400, worth every penny IMO, saves breathing smelly air from your compressor and also takes the load off it so you have plenty of cfm for your gun.
You can get 2k epoxy in aerosol, but its not really worth the extra cost to just save having to clean the gun.http://www.ebay.co.uk/itm/3-x-SPRAYMAX-2K-EPOXY-PRIMER-FILLER-BLACK-400ML-AEROSOL-SPRAY-2680034-/252349631050?hash=item3ac135ca4a:g:NDIAAOSwGYVXCPF1
He is wright, epoxy primer would be perfect, preferably 2k jotun 87 aluminium which you can put on with a brush. Regular 2k primer is not water proof, epoxy primer is.
Straight after acid dipping anything i will wash it down with water and then straight away while the part is still wet spray it with por15 metal prep and then leave to dry, doing it this way will avoid any flash rusting and the por15 will leave a coating of zinc phosphate which stops any...
I would have thought that the lower temperature would have thickened the viscosity though?
I thought the same, but i have sprayed the lechler epoxy at about 25 deg and it flowed out like glass with no runs, and just recently I did some other bits at about 10 deg and i got a lot more orange peel...
The more filters you can have the better, these filters work well,

As langy has said, why would you want to sand epoxy! that's not what its made for. You wouldn't order fish and chips and then complain because it doesn't taste like pizza :rolleyes:
