Concerned about wash primer system?

[San Migweld]

I am doing a bare metal repaint and the recommendation of my local paint supplier have used Lechler 2k etch wash primer followed by Lechler 2k Green TI primer/filler. I will then be using BSB base then 2k clear.

I am a hobbiest and worried I should have used a 2k epoxy primer instead of wash primer as it is very durable?

Any help would be gratefully recieved

You are a hobbyist. The system you used is probably what they think is more suited to your level of competence and will work for you.

Both are easy enough to use, maybe it's what the supplier is familiar with. He may not be a painter or praps not done it for donks and etch was the thing then or whatever. There are different ways to skin cats. It's a matter of choice in the end or deciding who to listen to, but the joys of epoxy have been mentioned lots on here. Sealer, inert, build, water proof etc.

yeah epoxy would have been the better choice , plenty of places using etch still

Thanks for the advice guys.

My concern is the fact I have wet flatted the paint and moisture may have found its way down to the steel?

Is it worth epoxy priming over the primer/filler before the base coat goes on?

not really , not on top of what youve done now ...would only seal in whatever is trapped

i used to wet flat a fair bit of stuff in my time at the body shop and didnt have any issues, if the car has been indoors and its just been done it should be okay , its usualy when theyre driven around in the wet they cause problems , if you have a way to warm over the panels then do so before painting

a brief blast with a hot air gun, primer changes colour when wet / damp

I made sure the garage was warm and dry and took care to remove the sludge and water asap.

yeah should be fairly safe then ..warm em up best you can so the panels feel warm to the touch
