Clear Lacquer

[jimbo84]

What do you use for clear lacquer straight onto steel?

I've used this stuff but it always goes rusty when the item is outside, I thoroughly wire wheel to bright steel and then clean with thinners before spraying but it doesn't stop the rust, had multiple things go rusty after being sprayed with this.

Ive tried loads of spray lacquers outside on bare steel they dont work for long.
Make one that works and I imagine you will become rich

Hb 496 2k clear lacquer.
It is a 2 part clear coat aerosol.
It does mean once used is pretty much the rest is scrap but it does work well.

I use Halfords rattle can clear lacquer.

I find it gives me decent enough finish for my needs.

Probably got to make sure any millscale is removed from the steel give it a rib down with 800 gritt paper and degrease properly, single pack probably no where near as good as 2k

If you want any paint to stick and that include lacquer, the steel needs to be abraded.
If you have a polished finish (like that left by wire wheeling) you will struggle no matter what you use.

If you can cope with a matt finish, a very fine media blast and then on with a two pack lacquer is your best bet.
If it has to be shiny before you start, keep looking and tell us all when you get something that works.

It always looks great once applied but just doesn't last any duration, sounds like most of you have had similar problems.

Is 2 pack the stuff that needs proper breathing kit and has the nasties in it?

 

[Dcal]

yes, but it's the nasties that gives it the performance.

you can use 2k with a decent mask preferably outside or well ventilated inside smallish jobs ok full wings and resprays no . 2k is the best hard and none porous

You can get masks that are suitable but it's a whole other can of worms that's not worth getting into.

Seems to remind me of a rather lengthly thread on the subject

make your own mind up whether to use it or not. there's enough information one way or another without the rather lengthy thread added
