Just wondering if anyone has had any experience with mixing clearcoat acrylic lacquer with acrylic lacquer colour to try and toughen the surface of the finished colour. I have recently painted my car in acrylic lacquer and I am having problems with the paint being very soft and therfore easy to scratch/mark.
I have done many acrylic lacquer jobs over the years and have never come acros this problem before, however the last solid colour I sprayed was about 7yrs ago. Has acrylic lacquer materials gone backwards in that time? I have done quite a few mettalics of late all with clearcoat and have not had any issues Any help appreciated.

I don't think it will make much difference mixing with clear and I think that the cold weather will slow down the process for complete hardening, acrylic will touch dry in about 10 - 15 minutes I suppose but the drying and hardening process will continue for maybe weeks to months depending on temp conditions, it will always be less scratch resistant than 2Pak as the 2Pak really is alot stronger as you probably know, but once we get in to some warmer weather your acrylic should become a bit harder, it also depends on the preperation, if you haven't got good stickability, (what a word) it will always be very scratch prone and you will find that it will scratch to chips and eventually flake away from the scratched area.
Im not a tradesman but sprayed 100's of cars over the years and altho I see the benefits of 2Pak I will stick with the acrylic for originality for the Torana and I am not one for safety gear so 2Pak is not the paint for me, I did use it when at a crash shop but acrylic is definately my favorite paint

Unfortunately it has already been drying for about four months so its as hard as it is going to get. Im regretting spraying it in acrylic now. But I 100% agree with what you are saying about two pack I much prefer acrylic especially for originality and ease of use etc. Ive got the paint rep coming out sometime this week to give his opinion so I guess I will see how I go. Ive never had any real issues spraying acrylic over the years. Typical if it's going to go wrong it goes wrong on my car. Thanks for the input.

I can not see haw acrylic clear can toughen anything.
The only benefit of additional clear would be a little extra to rub down.
FYI I was taught at TAFE that the thicker the paint the easier it is to chip.

I honestly think the quality of any Acrylic Lacquer that is available these days isn't improving, one of the other boys on here who painted his car in Lacquer reported the same issues.
I'm guessing the facts like there's no updating to Lacquer technology by paint companies and the less VOC's they're willing to put into solvent borne coatings like Lacquers aren't helping much.
I've also noticed the quality of thinners these days seems to not what it used to be, seems to be harder to flow lacquer these days compared to 8-10years ago without resorting to more Retarders or 2K Reducer etc.
I think a 2K finish that's been colour sanded and flattened out with like 1500-2000 and buffed back up resembles Acrylic Lacquer closely enough but still maintains more "structural" integrity if you know what I mean. But then again a nice Lacquer job is romantic:D

can i ask what brand of paint you used? I�m getting close to respraying my car and need to sort out what paint to buy or not to buy.
I used dulon on my first torana and still looks good after 9 years, I�ve tried a few brands since then with mixed results, Then used some dupont which i really liked and has held up well over a few years but they no longer do acrylic.
The last thing i want is putting a lot of time into the paint only to have it stuff up.
What brand would you recommend pete?

I used PPG Dulon formerly known as Dulux. I also used the best thinners you can get from PPG AAA thinners. I also used the same product the same colour about 6yrs ago and had no problems. Dupont make an acrylic lacquer it's called Lucite 400 I also had problems with this and had to strip it of my car the supplier that sold me the paint had put the wrong binder in it another brand instead of dupont binder and consequently it never dried and could be washed off with turps or petrol. I like all of the attributes of 2pak and have done 2pak resprays. But that was when I had access to a spray booth and and a nice SATA JET spray gun. I liked the fact that with acrylic it was as close to the original finish as possible, I can spot up with ease ,I can paint at home and I can get that beautiful shine lustre that acrylic gives the more you polish it the better it looks. But it looks like these paint manufactures should not be selling an inferior product if they have to reduce the quality so much because of VOC emmissions etc they should remove that product line. Anyway have to see what the rep from PPG has to say as I want to give PPG a fair go.

Let us know what he has to say.
I�m starting to wish I had attempted a 2 pack job, but no turning back now it�s all primered up and ready for paint. Just have to find the right product to spray on that will last. If they still made the old Dulux Acrylic I wouldn�t be worried.
I was told that DuPont don�t make the Lucite 400 acrylic from the paint supplier where I brought it from a few years back.
That�s what I used to spray a 4x4 I have and its held up really well. lots of bashing through scrub, scraping braches etc. has put it to the test. I might have to ring around and see if I can get hold of it.
Cheers drew

I've used Spartan for the last couple of years and always had decent results.
With the softness and chipping, my guess would be the binder component of the paint might be getting affected somehow, either by the thinners not being as compatable as it should (unlikely) or the actual ingredients used to manufacture the paint not being what they once might have been? Then there's always an incorrect film build ie. too thick an undercoat or topcoats etc that might have been to blame?.
If there's a definate answer to come out of it please post it up 71xu1, although my experience with paint manufactures is they don't like to and won't ever admit any fault on their behalf "on the record". The best you could hope for is probably another tin of paint for free if your lucky!!
