White Patches In Acrylic Paint From A Can

[made_guy]

i was doing a dodgy paint job on the lower lip of my spare 400r bar last night (painting it black).

I'm just using the repsol acrylic from supercheap and i noticed in a couple of places there are white-ish/grey patches....

Why do i have these and how do i get rid of them? i put on 3 coats and they were present in the first coat and are still there now.

now being a 'dodgy' job, i didn't clean everything really well (one spot has a few crackles/bubbles....gonna need a bit of a sand on that bit). i did give it all a light sand also and forgot to wipe the dust off....impatient AND dodgey!

anyway, not a big deal, just wondering if there's an obvious reason.

only post if you have experience please not cos you "reckon it's probably cos of" or "i'd say it's" ...... i know i did a heap of dodgy things, but there are only a couple of patches so i'm thinking there is a 'proper' explanation.

you've answered you own question, sounds like you didn't clean the surface properly.. oil from your hands possibly...

i'm pretty sure it was just where i had held the can too close. but my uncleanliness sure didn't help.

the patches seemed to disappear overnight anyways so i'm happy.

what a mission it was to install the front bar though!!

cut reo

fit reo back up

try to fit bar

make bolt holes a little bigger

cut reo some more! while it's still on the car cos i was getting frustrated (+dodgy)

cut hands

fit bar!

can't get in to tighten bolts!

cut little strips off the back of the front bar to get ratchet in there

tighten up!

looks a little flared because i need to widen the holes a bit cos they don't line up properly but it's on!!

then i realised my tyre was flat!!?! MOTHERF*CKER!!!!!!

sprayed when the air might be too cold(moisture)......I did that when I was sprying a coat of clear on my spoiler of my old VL.

To much moisutre my friend...

If you insist on spaying on a hot humid day or a wet raining day or the day after it rains.. Do so in the bathroom with heatlamps on.

Also heat the spray can in hot water in a bucket for 2 minutes before spraying as well as maintaining the correct distance 20cm from the object.. this will make your white spots disappear.

Now all you have to do is sand it down and spray again..

Just so i dont make another thread, just wanted to ask.

I bought some acrylic paint that needs to be thinned out. How long do i have to wait between coats with acrylic paint? Same time as acrylic paint in cans?

Also about the handling of acrylic paint thats been thinned out. Can it be stored in air tight container if too much is mixed?
