800 is not enough. Its your prep I am afraid.

I use 320 before primer and 600 before a basecoat. I learned the hard way with that helmet as I used to use 800.

tha last helmet i did was masked and painted in a similar way ,i laid autoborne black as my base then the mango AA then masked off for the autoborn grafix ,i did have a good step in places but the mask came away clean as a whistle without takeing the grafix with it like happened to you

i use P600 for AA i dont realy trust P800 especialy when building high as AA relies soley on a physical bond and i find it covers P600 just as well as 800 anyway

try preping with 600 and see if it makes a difference

BTW what where the cases made of ?

well i posted that without reading kats and Johns answer ,as a sprayer im used to useing P800 for basecoats especialy pearls but AA covers 600 very well ,one it gives a superior scratch for adhesion two it makes life a little easier workwise

as AA covers 600 so well then there is little to be gained by useing 800 anyway

800 is actualy concidered a very fine paper and about the finest you could rely on for paint adhesion ,it is only realy required becouse of pearls or if useing old cellulose paints that sink back

for the actual bond issue then the rougher the better untill you get to the point where it effects the finished results

im not tryng to teach my granny to suck eggs here Stu but most folk are useing 600 for AA ,it did take me a while to get my head round this being used to basecoat sytems but AA doese not sink back into the scratch marks nearly as much as solvent paint

The think that messes it up even more though:

Yes I used 800 on this but I can still see all the scratches in the basecoat so it didnt cover as well as the old stuff.

I prepped the van with 1200, then 2000 wet and used autoborne - none of it shifted at all and we cleared over it with not a prob.

Perhaps its just my bad luck.

I shall speak to my paint tech guys tomorrow and see what they say.

i've had the same issue today, on a well prepped panel :angry:

my simple solution is to throw the AA in the bin and move to another paint brand. I've tried and tried with AA, thought i had it nailed, not had a problem for ages with it, but this was the straw that broke the camels back. I'm not going to spend any more time or £'s with AA

imho..i use aa for pretty much everything..
but as i only do it for a hobby my technique probly wont work if you have a small time window..

ill lay down the sealer,then the base,a dusting of 1k clear..
then in between layers of art..pre-scuffed..more 1k..just to prevent paint lift..
then once done..another scuff and 2k to finish..
but without the 1k clear i do get paint lift issues... :D :D

hmm only just saw this,i only use autoborne,and i use masking film alot,i use ultra mask,only trouble ive had lately is the masking itself leaving a residue on paintwork whick i hadnt painted,that was the celica,bumper had just been done in hok candy,was baked and left 2 days,only way to remedy was lightly sanding the candy,nothing would remove the residue,i wonder if theres a prob with ultra mask maybe?as for sanding ive always used 800,in the case of the celica i used it dry and when i did the purple there was a hell of alot of paint on there with the masking,but no lifting issuses?im at a loss,but keen to know what is the prob when u find out?

EEEhh, I hate Auto Air, same probs over here, even when the prep is done right. Sometimes it works and sometimes it does what it wants. I hate rolling the dice on a good project I'm working and it peels off with the mask. I was doing a simular job with the old school flames and that happened. I did it with HOK and it took half the time, I spend more time fixing the issue with AA.....i guess it's for some people.. :afro:
