help understanding paint types!

As said rust bullet is very hard once cured and not suitable for springs, so no wonder it rusted. It does have to be applied thinly. Give them a call, there should be a number on the instructions somewhere.

i used it over some cleaned up scabs , didnt last any better than household paint

the way i see it ...clean it properly and any decent primer /paint will keep it nice

if you wont /cant clean it well , then any old slap will keep the weather out and just redo it in a few years

Thinks you been on yank forums too much, yr best on UK ones where folk talk about what works, what's available, and using UK terms eg "urethane" isn't used hardly.
Etch or epoxy + topcoats of choice is the tried & trusted way.
And 1k acrylic is aka 1k or just 'basecoat', you'll have no bother finding that.

As for oxygen cylinders and price of hire... What price on your health? And what are you going to do when it runs out halfway through a job?

yeah i am on the US forums! for my mg and i must say they have been fantastic with information! although their jargon has confused me reguarding paint! why is paint called different things in different country's!
anyway you have talked me round to epoxy primer! can you get 1k epoxy primer and can i put basecoat (1k acrylic over it) and then u-pol 1k smart clear?

chipper i thought you didnt need oxygen with 1k? i will have a very basic down draft setup in a marquee in my garage!

and just for reference what on earth is urethane paint? i thought urethane was for plastic bags!

thanks again guys!

You could use a high zinc primer that will work on 10% worth of rust, but it's best to get rid of it all to be sure. High zinc primer doesn't really stick to bare steel very well ime but as its been sandblasted it will have good adhesion.

As for the oxygen tank, they have a certain amount of time of use so im sure you can calculate how long to use it for the job. I would rather spent the money if it was cheap enough to buy my own mask then buy the oxygen tank, over £100 to rent them both for one day. I dont have room for another compressor for the clean air you see.

No oxygen for 1k needed but for 2k epoxy yes you do need a good air supply for it at all times. 1k just needs a good quality mask.

The thought of trying to get round a car wearing an air tank is pretty amusing. There's a reason why no-one else is doing this, praps when you try spraying you'll see the reasons why it's impractical.
Maybe you could put a comp outside a garage, boxed with filtered intake etc.

Pants, no need for oxygen, no-one uses it. But 2k ideally wants an airfed system - positive pressure mask, keeps the isocyanates & fumes out. 1k you can use a good mask, be sure it fits. Some people do use chuckaway masks with 2k, but when it goes wrong, it can go very wrong.

Not heard of a 1k epoxy but there's a non-isocyanate 2k epoxy by House of Kolor, know nothing about it except it's got a hefty price. You could indeed 2k epoxy, 1k colour, and clear. Do you need clear, if straight colour you could use celly and cut a stage out.
The Americans seem to call 2k 'urethane' btw.

oh im painting metalic silver!

 

[Chipper]

i thought you didnt need oxygen with 1k

O2 thing from here mate but hey no worries.
Just check all the H&S with 2k epoxy, the stickies here and all that stuff, or be sitting down when looking at the HOK price if thats what yr thinking
Are you going to do a thread in projects, there's a couple of MGs on the go here too so you'd be in good company.

 

[pants007]

yeah i will put up a project prob titled 'WHAT NOT TO PAINT YOUR CAR WITH'

i dont have a clue about paint company's! what product do you use? i went on the house of color web page and it was all 'french' to me!

give me a run down on the products i will need to paint my car 2k epoxy-1k metalic base-then 1k clear?

do i need to use high build primer? or is the 2k epoxy a highbuild primer?

what quantities do i need, its not a massive car and im still going to use my rust bullet on the floor pans and engine bay as its silver to!

thanks for you help again!

 

[steveo3002]

id suggest you sit back and read a few threads /forums and get the jist of things

its sooo much work to ruin by rushing in and buying the wrong products

 

[pants007]
