aerox panels reacting when painting

iv noticed aerox pans are made of a diffo black plastic to like nrg zip runner pans ect and when you sand the pans down on an aerox so some bits are paint n some are the plastic then apply primer it doesnt adere well and wrinkles up .why does this happen on aerox pans but not piggy .im using cans from halford by the way how can i stop it reacting .primer normaly doesnt react with oat but it doesnt seem to agree wiv my rox pans .
can any help. thanks v much nibs

 

any one .jefro ur the pan man lol got any ideas how to stop it

 

cellulose red oxide primer ftw

 

thx boys

 

As above nibbles.....What did you use to sand down, any liquids or anything?

 

yerp lol water n fairy liquid. y i dont no lol ma bro told me thats wot he used to do when he was a panel beater

 

Yeah not before paint though lol, just use warm water. Careful what soap you do use though as it can react. Fairy is fine

 

ite man .to be fair if i want so lazy n sanded the whole lot like minor said itd be a lot easier but its a lot of man hours just to sell the bike cheap i h8 sanding i mean fukin h8 it wiv a passion iv done so much of it .any one wanna buy me a d.a for christmas lol

 

ite man second i get out of my mum n dads fekin shop ill get to it .iv been sat ere to look after the shop while they go for some bloody meeting.the one day i get up early to do the bike lol they sit me ere like some rent boy .
thanks for all the tips

 

I might do some down the shed today too but it's getting fooking cold. My sander looks like a mini iron lol, but I generally just do it by hand. From scratch I sometimes use the sander though.

 

yh whats the lowest you should go teperature wise .i warm the pans up slightly n the paint 2 just to help it along dunno weather this is reccomended but it seems to work .yh typh pans are pritty flat arnt they not to many cuvry bendy awkward bits .i find piggy paint sands off easier aswell compared to rox

 

i tried to paint me ped at the weekend and after i rubbed down and washed it i primes it. it started to react! like crinkle like there was paint stripper on it.
so i had to take it back to plastic. its a right bastard!
if you have to do this watch out for parts like your front mud guard and inspection pannel. they are full of filler and react quite badly.
like the filler goes sort and its harder to get the paint off.
dont use paint stripper ether i learnt my lesson

edit: dont rush or cut corners!

 

thx for all replys

 

wot issit how dussit work n how u got so much bin stockpiling lol

 

o and wot does the soap actualy dooo ma bro never did say
