Edit: Manually moving a car with a locker isnt that much fun. Especially manouvering it out of its space in the shed. Locker < LSD anyday

It's coming along nicely mate :P

 

keep em comin

[SLO-030]

Thanks -=KE30=-,

 

I'm really stoked at how the window filler section looks. Better than the stock ones on the panel vans IMO

 

CHEERS

yay for more progress :P

 

congrats

I definitely need to borrow that compressor aye ryan. I use mine for 5 seconds and it begins to lose pressure. Cheap piece of rubbish. So you're painting this in acrylic yea?

[SLO-030]

Its not my compressor Jase,

 

But that said, I'm chasing up a big tank as i have a REALLY big compressor unit lined up.

 

This one we used is just a single piston belt drive and never once did Luc nor Myslef have to wait for it to build up pressure. Whislt all spraying took place, the tank pressure never dropped below 300kpa

looks good but ya got some flatties :P haha

 

window sections do look really quite good!

[SLO-030]

jase the primer is a 2 pack.

the base colours are acrylic.

the clear is a 2 pack

[Murd 55]

interesting, i was under the impression that while you can paint acrylic over 2pac easily enough with no issues, you shouldnt paint 2pac over acrylic if you want the results to last, was told this by the tradey at work. so might want to look into it.

Explain your reasoning.

ok. according to the paint tech at work you can do it.

the notion that you can't come from the acrylic being a sovent based paint. and to dry the solvents need to evaporate. this evaporation is what can cause the 2 pack on top to crackle or bubble up.

this has come about by looking at older car and you see the clear coat peeling away etc.

also that the acrylic paint is 'soft' or moves as such.

 

 

to answer no.1

the acrylic needs to be allowed time to properly dry. at least 24hrs... also depends on humidity temp, etc. it can take up to a week in cold temps. in a crash shop this isn't real feasable....

IF the solvents have completely evaporated then there is no problem with it.

 

older cars were painted using older style paints.. new clearcoats have a lot better attributes to them. Du Ponts oe8000 has an incredibly high UV rating which will protect for years more than what the older paint would've.

 

no.2

Acrylics are a soft media. unless hardener is added. but in most cases you don't use it.

so to stop the paint from 'moving' you sandwhich it in between 2 hard surfaces.

2 pack primer

2 pack clear.

 

this is used quite commonly on cars called a 'tri coat' finish.

 

To simply assume because of older paint systems that have failed after 15yrs that acrylic is a no go is silly.

paint has come a long way since then.

 

Crash shops etc commonly say it can't be done because thats what they are told... but this is in their circumstances where they can't allow proper time for everything.

hence why 2 pack colours are widely used at crash shops. because it a quicker process overall.

 

DNA is a reputable company and their basecoats are acrylics.... you can add hardener but it isn't a necessity. and you still use the same amount of thinners up to 75% its just there to

quicken the drying time.

 

I have done a lot of reading on this... the general theme seems to be yes you can, no you can't. Mainly from tradies in the 'Crash shop industry' or DIY'ers

so often tradies are fighting on paint forums about this subject.

 

i choose to do this as my work is an industiral painting factory and this is a very common process to use coming direct from Du pont, PPG, Protec, Jotun etc who have all spent squillions of dollars

developing painting methods. and also our company has done a lot of work for holden and mitsubishi.

 

but again everyone has opinions regardless of proofs or experience and every tradey thinks they know but even they fight about it.

just to add to the above upon more discussing and research a lot of modern cars a now painted with this method.

the possibility of the paint failing is very real if it isn't done right. but.... in saying that manufacturers now more often than not when using that paint method

bake the paint after laying the acrylic. this eliminates ALL possibility of the sovlents still being there and hence reacting with the chemical 2 pack.

 

comparing 15yr old paint methods to what we have now is like comparing apples with oranges

[Murd 55]

we can't as our 2 pac is water based. can't use water based over solvent based. but yeah i would agree at our work some jobs are primed painted cleared polished and gone in one day.

[Jason KE30]

I'm plannin on doin my ke55 with all 2pac, eg. primer, base and clear. Gonna cost me a fair chunk out of my wallet but the quality of the paint job will come up tops. What brand primer did you use??
