Drew I thought i would expand my reply further as Polyester spray putty is funny stuff, It sucks up moisture like a sponge so its essential to get it on in a dry atmosphere and get it flatted quickly and then cover it with some epoxy, Its very useful stuff on fibreglass but i would avoid using it on steel bodys if you can.

Repairing the sills on my son's BMW E34, long job and obviously twitchy about rust coming back. Epoxy primer seems to be the way to go but I don't do enough spraying to justify a compressor and an air fed mask. Is there a 1K version that comes in a spray can or am I best sticking to the etchweld primer I have been using?

The beauty of the 2k epoxy is the way it sticks and hardens, i'm not sure the 1k epoxy will be as good, not tried it myself as i always use 2k but if the 1k was as good there would be no need for 2k.
To be honest and its only my opinion but anything in an aerosol will never come close.

Would it be possible to roller the epoxy instead of spraying it? It would mean you could get away with an organic vapour + particulate mask.

brush it on best you can ...smooth it slightly without roaring it all off , then use ratlle can primers to finish it off
ive been using epoxy mastic primer , its thick enough to fill pits n grinder marks and then sand smooth with 180/240 and finish as req

Hi guys, sorry I've jumped in a bit late and might have missed this but does anyone know the stages after using an epoxy primer, I've just bought some of the Lechlar epoxy primer and wondering what comes after as i'll be leaving it months before going to paint, is there something I need to do to make things easier as I've read some places that top coating straight onto the epoxy isn't the best idea as it may cause inconsistency in paint or paint peel.
Some seem to suggest sanding and coating with a 2 part primer/surfacer and block sanding before going over with a top coat for best results.
Others say it's ok if you just sand and spray a more thinned out coat of the epoxy primer then coat with the top coat within say a few days or a week.
Any ideas on what's best?

Hi all, I've just registered to post on this topic so thank you for all the info so far.
I've got a VW Camper going to be blasted shortly, and I'm just trying to decide what primer I should get laid down when it comes back - etch or epoxy?
There will be repairs to make afterwards, so will epoxy be difficult to key after being left for a couple of weeks?
I want the absolute best corrosion protection for my vehicle - I don't want to have to go to these lengths again at any time soon!

Lechler epoxy
Hi, just a question about the Lechler Epoxy 29107......
I mixed 500ml 29107
250ml hardener
25ml thinners
I tried it out tonight and was surprised that when sprayed, it has almost no colour, even though it is gray in the spray gun! Is this normal? For some reason, I presumed it was going to turn out a more solid gray like normal primer.
Thanks,
David

Hi, it does normally turn out a solid colour wich covers really well. Have you had the epoxy mixed or straight from a shop as epoxy needs tinting to users colour preferance. I buy mine from a local supplier and the first question they ask is what colour would you like it, i also have it grey. Im sure the epoxy comes to the suppliers as a clear binder and they tint it

I got it from metalflake.com, they never asked what colour...I'm sure it said gray somewhere so I just presumed it was a more solid colour and not so transparent. Its possible I suppose that the gray colour is just from the zinc content and there is no other pigment in there... I'll email metalflake.com to ask them...

I've had 2 lots from Metalflake and its been exactly the same as yours.
You should get coverage with one coat with Epoxy.

Most Epoxy you buy is grey, Its only if the have a mixing scheme you can pick the colour.
