2006 Cooler Master Mod Competition

minimum order charge of £30, including polishing the front panel, anodising and postage back

The front panel originally had some scratches which i sanded out some time ago and was left looking like this:

 
Argh disaster has struck! i've been putting on the colour tonight and for some reason there are certain areas on the side panels that have reacted and look like i've sprayed paint stripper on them!

I'm going to have to start all over again!

Any one got any ideas what has gone wrong - i'm using plastikote super primer in grey and a plastikote metalic colour.

I stripped the panels with paint stripper washed them down with warm soapy water and dried off. I used panel wipes from halfords prior to priming.

I then sprayed one coat of primer front, allowed to dry and sprayed the back, the panels were left to dry for a couple of days, yesterday i wet sanded washed off dried and the panel wiped before spraying the second coat of primer.

Today i wet sanded again washed off dried and panel wiped before spraying the colour.

The PSU case is fine and completed now, but the side panels have reacted.

Is it possible something was left on the alu and has come through the primer and reacted with the paint?

Also the colour didn't go on nearly as easily as the primer did - i was lulled into a false sense of security!
 
haribo,
sounds liek your havvign a rought time !
i havnt read thorugh all the thread yet

but the most common paitn reaction is due to silicone.

silicone is in a lot of things these days - polished, sealants, 'tyre shine' compounds etc etc

silicone spells utter disaster for paint. somtimes making it just slide off a surface like a snake shedding its skin !

is it possible that yove had any products containing silicone near the project ?

pics would help me diagnose it though.

***EDIT***

i was talkign to messiah khan about a similar reaction caused by paint drying at different rates.

this reaction looks like the OPPOSITE to the peel of an orange... instead of dips, there are tiny little spikes and wrincles that looked like similar to pinching a table cloth and pulling it up ( thousands of times )

that reacction is mainly caused by the paint underneath dryign at a different rate to the paint on top - did you force dry the paint ? use very thick layers? or apply fresh paint ontop of still tacky underlying paint ?

if so that could be the answer
but id still need to see pictures really.

( aerosol paints are known for causing hell by the way ! your not the first )

Willpost some pictures when i get home, the last coat of primer was done yesterday evening around 7pm, and i started painting the colour coat about 4pm today - so i think the primer should have dried ok
 
no force drying was done heres the pictures





It's a total disaster, i've just tried to strip this stuff off and the back of the panel which is primer is just smearing around not blistering like paint should, it's like adding water to a water based paint - the panels are wrecked :(

The top panel and the PSU case are fine but the two side panels :( there must have been something on then, even though all the panels were treated the same and all done at the same time.

I'me really liking the colour and how it looks on the good parts but i think that i shoukd have gone with a different spray as this plastikote stuff seems even though dry it marks with a finger nail it just seems too soft.

supposedly the primer is touch dry in 10-20 minutes and thoroughly dry in 30-40 minutes. the metalic is touch dry in 5 minutes and thoroughly dry in 25-35 minutes

The first coat of primer was done on thursday night, it was sanded and washed on sunday morning. Sunday late afternoon evening the second coat of primer was applied. late this afternoon it was sanded again and washed, dried by hand then the metalic was sprayed on. So i think i've given plenty of time to dry ?

I'll have another look in the morning when there is better light, it's hard working out side in the dark with poor lighting.

I'm actually really upset about it as it was all going really well, and i was so chuffed with the way the primer went on nicely - very very deflated now!

dont worry mate ! welcome to the world of painting. its happened many a time to me. and you just learn from your mistakes.

dscf1060oo8.jpg


that is EXACTLY what io was trying to describe
but it looks like youve got a couple of reactions there. the paint merly sliding off is ringing alarm bells for silicone being present. as usualy the 'crazing reaction or 'wrinkling'' ( the mad texture thats come up) usualy dries and stays... and sometimes quite hard to sand through - so its odd that its just wiped off.

the reason for the wrinkling is that you have applied your paint too thick, and possibly the conditions were a tad too cold.
what happens it the surface dries a film over it while the underlying paint is still wet. as it dries throughtout it causes the top 'skin' to wrinkle up and look awful.
the reaction being in the middle of the pannle also tells me somethign about your spraying technique. it appearss you may have gone a bit too heavy in the middle of the pannel which is why this has occured.


5 ways to avoid this happening again:

1: be patient and never apply too much paitn at once, the first few coats should eb a 'dust coat' never aim to cocver the whole pannel in one go.

2: mix your cans well, the best way is to hold the can at the top, and twist it round so that the ball 'runs' around the bottom of the can. - this will eliminate the possibiolity of inpropper mixxing and un even coverage of the paint its self.

3: avoid painting in the cold, and possibly moise environment ( move to spain lol )

4: avoid paintign in very HOT conditions ( move back to england) - this will only make a skin develop quicker and could increase the risk

5: said it before... ill say it again
take your time, have fun !


hope this helps

Cheers Rick, the contest deadline has been extended two weeks so i should be able to get it sorted out by then.

"Dust covering" thats interesting, your right I do tend to spray so i can actually see the covering - will try next time to go a it slower.

Also on talking to platikote "tech" help they have said that i don't have to use primer on alu and that i can spray direct - is this advisable? I don't think i'll take this route as the top panel has been done and it looks good, and i think the side panels would look different with out the primer.
 
im speaking out of turn here as really you shouldnt spray amnythign onto bare metal without 'propper' primers lol. but i wouldnt imagine not using a primer will help at all to be honest.

the problems you had were ntohgin to do with the primer. it was all to do with the blue coat.

metalics are a bugger to ghet right so the best way is as i said. dust coats.
you should always be able to see the original colour throught your first coat, and apply the second coat in the same mannor, until all the coverage is even and smooth.

it is THE most common mistake to just cover it in one go. hell i still do itt from time to time :eek: lol

if you need any more helop just give me a shout ;)

had to use white spirit it was the only way i could get the grey primer totally off.

I did have panel wipes which i got from halfords. but the last were used up today - i'll get some more on thursday.

So what should i do to make sure that all the white spirit is off and not left anything behind, i have washed the panel in warm soapy water

just giev it a good cleaning with soapy water. its the best you can do tbh.

pannel wipe and pannel wipeS are different. pannel WIPE is a liquid wax and grease remover. whilst pannel WIPES are probobly the halfords rip off for 'tack rags'

( unless ive gotten the wrong end of the stick )

Probably are a rip off but it does say:

Water based pre-saturated wipe. Ensures the surface area is free from all traces of dust, grease and other contaminates

Hmm 5ltr cans of "panel wipe" pre-paint wipe for £16 at auction
