how to get smooth clear of the gun

[Linzi]

I recently sprayed my ss skirts myself in Acrylic. It is a metallic colour so I had to put a clear coat over the top. Problem is it come up with a fairly major 'orange peel' kind of finish. So I rubbed it back with some 2000 grit and cut and polished it. It came up fairly well, but loses its shine pretty quickly. I'm wondering how to not get as much 'orange peel' so I don't need to sand it as much. Also some of them blistered In a few spots, it looks like little spots in the clear, and the clear still seems soft when it's in the sun some times. Any help would be great thanks.

Sorry but YOUR bubble is 'bout to be burst.


YES you do put clear over acrylic lacquer, especially if it's a metallic.

"2pac is what you put acrylic over" What the hell does that even mean? Have you put acrylic over 2 pack?

Have you EVER painted anything....PROPERLY?



I wish people would post when they actually DO know something 'bout the thread.


Buddy, your post is just one major fail.

2pac needs to be cleared, acrylic does not.

OP, you're doin' the right thing (good on ya for having a go)

Give the side skirts a couple of weeks to harden (acrylic lacquer uses evaporation to dry, meaning it's not hard 'til all the solvents have gone, where as 2 pack relies on a chemical reaction to harden, hence the hardener)

After they're hard, scuff them with 'bout 800 grit paper (wet is better than dry) then re-clear them.

If you're using a spray gun, thion down the clear a little more than you did last time.
If using an aerosol can, do lots of light coats.
You don't want to put it on 'heavy'.

After that then 2000 and buff / polish.



Don't worry mate, acrylic lacquer is a pain and very time consuming.



I did my time (early '80s) using lacquer and i hate using when i have a job that requires it.

You've got that backwards i think.


But then again i may be wrong..........................gosh that means my 30 odd years in the industry have been a waste of time.

Here are some tips I got from a few Tradesman spray painters. I have also sprayed acrylic several times myself.

BY using Acrylic thinners rather then Multi thinners in the clear you will get a smoother finish. Also by lowering the air pressure to about 45psi when spraying the clear.
Having the gun setup properly with the correct fluid to air ratio will also help gat a smooth finish.
Use 1200g or 1500g when sanding the clear not 2000g. You will see small dimples in the sanding so make sure they are all gone before you buff. (the compound will get those scratch marks out)
Using the correct acrylic buffing compound and waiting at least 3 to 4 days before sanding will also stop the clear from getting imperfections in the future.

By waiting 10 min between coats can also help with problems in the future as the solvent has time to dry before a new coat goes over it.
By using a little bit of retarder thinners in the clear will slow the drying process and help with gloss.

Its funny that someone said acrylic doesnt need clear.. Thats sooo funny. Forums are such a reliable place for correct information arent they.

I have some instructional videos on this subject try google my name to find them.

Please tell me how 2 PAC doesn't need to be cleared?

[CustomSprayMods]

Please tell me how 2 PAC doesn't need to be cleared?

2pack has 2 systems. One has solid colours that need to be mixed with hardener and thinners only. it does not need clearcoat.
The other is a basecoat system it has solid and metallic/ pearls. It needs only thinners. It also needs a clearcoat to be sprayed over the top and hardener only goes in the clear.

LOL! um.. because you can get 2k in a solid colour??


whats with all the retards in here?

clear over base in available in BOTH acrylic and 2k
solid colour is available in BOTH acrylic and 2k

i have found that having my shed as hot as i can get it, then spraying thick coats (ie less reducer) generally gets the clear nice and flat, but it gets prone to runs so you have to be careful of the corners. the other way would be to just use a thinner mix and wait a lesser amount of time between coats.

also you will find that 2k will last a zillion times longer before you need to polish it again.

Here ya go 3 different paint systems Acrylic, 2K Solid & 2K Basecoat

Shit sorry tuff ####, when I use 2k I clear it but when paint at home I use acrylic. Never had a problem with not clearing acrylic either. Have painted 1 car and my old man is in the process of another using acrylic.

Of course the painters are going to no alot more than me, I only do it as a hobby.

LOL sorry i was tired when i wrote that, i meant 2pac is what u put clear over, if you were smart enough you couldve figured that out but anyway

[Linzi]

Haha cheers for the help. Got me a bit worried there at first Lol. I'm thinking bout respraying my bonnet myself. Good idea or get it done properly?

[pjdm1980]

I am and I did!!!!! Ba ha ha ha ha

[ari666]

depends on if you got all the stuff to do it. also just remember you will never get it perfect, so as long as your happy with it looking less than perfect i say by all means give it a shot.

edit* also the little "spots" in the clear could be fish-eyes. little drops of water and oil from your compressor. you need to get a bomb-diggity water trap to stop that happening, and always drain all the water out of your compressor before you start.

When i lived in Brisbane i went through a stage of "fisheyes" in my shop at Slacks Creek.

So i re-newed all the air plumbing and started using a decent "fisheye" additive.

Nothing worked.........you know what it was......................the airbourne sap and crap from the poxy gum trees out the back of the shop.

Lol. I've got exactly the same problem at the moment. Fighting with the council to get them removed.

[ari666]

lol, good luck with that!!

[hi_ryder]

i wouldnt paint a rubbish bin wit acrylic...

Can actually get very good results with it.

this is one of the funniest threads ive ever read acrylic is the simplest material to use and is equal to 2pac under most conditions people just have to realise acrylic takes around 128 days to completely release its solvents so if you can wait that long before you buff polish or wat ever thats when it will hold its maximum gloss , and as bellicose has said if you ever used 2pac back in the early 80s it was total crap , ive had 35 years in the trade and can only laugh when people claim poor old acrylic is shit cause its really a bloody good paint if applied correctly it is easy as to touch up no scuffing edges and the likes just blend it in so much easier for the less skilled of us to do , plus buff it with a bit of the old carplan TCUT and it will shine like glass its best buddy is a bit of retarder thinners to help with flow and gloss off the gun , its also a lot less harmful to the human body as well no iscocyanates nast little buggers these are known to build up in the body over time and can make ya pretty darn crook .

Finally. Someone who knows their acrylic. I did my apprenticeship when 2 pak was only first coming onto the scene and everyone hated it. The tradesman who taught me would swear by acrylic and used brasso to cut new paint with. I ran into him a few years ago and he's still doing a few odd resprays ( in acrylic of course) and he's in his mid eighties now.

There is a shop in seven hills in Sydney who still uses acrylic. And we have been doing free lessons on acrylic once a month for the last 3 years and get up to 30 people every time. Not everyone has a booth so its perfect.
