2 pack is not as flexible as acrylic
acrylic is porous.. but only the primer....
it is illegal to use 2 pack at home.

Aaron, I believe 2 pack clear is incompatible with acrylic lacquers. You could use acrylic clear though.

BTW, 2 pack hi-build works OK under acrylic. Non-porous too. And it's not near as nasty as 2 pack topcoats. :wink:

inazuma_x judging from your previous posts and from what i've gathered you want to achieve the only way to go is 2 Pack.

A Good quality brand 2 pack if looked after well will last forever, Acrylic Laquer always needs attention to make it last.

I personally think there is less work in a 2pack job, surface prep is the same no matter what type of paint you use. There's no rubbing down between coats with 2 pack compared to Acrylic and no need to worry about rubbing everything down and buffing if your booth is clean and your painter is top notch.

Acrylic paint is excellent for the home user as its relatively safe and user friendly, Most panelshops dont even have a full Acrylic paint system anymore and if they do and thats all they use well i probably wouldnt have my car repaired there.

Professionals Painters using acrylic for restoration work would only be doing it to replicate an authentic finish on a car, there isnt too many painters worth their salt who would willingly choose acrylic over 2 pack.

If your paying someone to paint your car i'd insist a premium 2 pack finish using a quality paint system like Glasurit, PPG etc. You wont be dissappointed.

excellent info

thanks! i've heard from EVERYBODY (both here and in the flesh) that 2 pack is the way to go...i think the answer is clear...2 pack

Are you 100% sure. Maybe I am being misled but i was told by repco when i bought some paint that i could put a 2pack clear over the top of a acrylic base. this i have done with some flares for putt putt, seem to work ok, has a good shine. What will happen if it isn't right?

Cheers

Aaron

aaron, re the clear coat,
Only what I've heard and read. Check with Brad, he's used both on his various cars lately.

You can spray 2-pack at home as long as you use an "Iso-free" 2 pack as it is not nearly as deadly when inhaled :shock:

but you should still use a good mask, and iso-free can air dry, no need to bake it.

I got some HiChem (they are located in victoria) brand iso-free clear (they even had it at supercheap) to lay over acrylic silver on my wheels, came up a treat and glossier than you will ever get an acrylic.

HiChem has product data sheets on their web site

Hope that helps.

I have a friend who is a spray paint tech teacher and he was telling me all about two packs vs acrylic. Regarding the toxicity of the paint; it is not only fumes and breathing that are the problem, this stuff enters the body through the skin pores and eyes. Don't use it at all unless you have a spraybooth though I am sure it has been done. He also said that it is possible to match any two pack finish with acrylic if you want, though I bet I can't do it. The non water based 2 packs are banned in Europe and the US for good reason.

I've just bought some hi fill 2pac primer to go over my dodgy por15 repairs which haven't feathered out neatly. As suggested by feralsprint on another thread. Thanks for all the good advice BTW.
Its fantastic to use. Much easier to get a good finish. I'm a convert now for sure.
But is hifill really dangerous? ( I'll be using acrylic topcoats )
I've been spraying in my garage and wearing one of those two filtered resipators.
Does that sound safe enough?
Cheers
Dave

The highfill primer is not to bad but do wear your mask its basically an acrylic enamel primer thats why you can use either paint over the top

just reading up about 2pack clears. There are two types. 2pack solid and 2pack clear over Base. The 2nd will stick to acrylic. I think this one is a Iso Free type. It looks like it is what i have used on my flares, shine is nice and looks pretty good for someone that hasn't got a clue. We will see how they look in amonth and see if they peel.

Cheers

Aaron

That's a relief then.
I won't die prematurely before paint job is finished.
Probably just die of old age before paint is finished.
Thanks
Dave

2 pack hi-fill is an epoxy based product... not acrylic. :wink:

But acrylic top coats are fine over it.

Basically anything you spray is bad for your health if you dont take the proper precautions........and/or then go and do it in large quantities

Also, basically all paints are porus to some extent, it just depends on whose paint it is and what the type of paint is as to what the extent of the porosity is. Most of the time its negligable though.

This would be MOTORSPRAY brand paint. It is made by HiChem. I don't rate this stuff at all......it's **** in my opinion....and the HiChem people are ****** to deal with.

I am speaking from experience.

re: Acrylic. Why is everyone so obsessed with 2K ? I painted JAM in acrylic, and have painted other cars with acrylic in the past.

The key to a great shine is PUT LOTS OF COATS ON!!! Don't be lazy.... With a heap of paint on your surface, you can rub it back and buff up a great shine.

The next car I paint for myself will again be ACRYLIC, although I will use DOUBLE the paint.

Also, BRAND MATTERS!!! Good quality paint (PPG for example) will give beautiful results! Cheap paint (Motorspray for example) will give cheap results....once again speaking from experience!

So Anton you don't suggest I paint my new car with an arcrlic base coat and a clear 2pack over coat? I will try and get it painted by a pro but funds are an issue so i may have to paint it myself. Being that it will be black i know the panel work needs to be spot on. My issue is that it is black, hence why a clear coat over the top may just help it from getting distroyed in the first motorkhana i do.

Cheers

Aaron
