Ok so i have tried to paint my splitter and found that the BS7 Paint is reacting with something.

my dad mentioned i need some sort of sealer, can anyone point me in the right direction of what i need?

Thanks
 
ive had this problem with my bumper... what primer have u used?

i used a HOLTS one (i think) but its reacted with the top of the bumper?

just halfords grey primer.

i reckon this stems from the fact i accidently sprayed white onto the splitter. cause the paint reacts and shows white cracks
 
You should still never attempt painting a surface without first properly preparing it, by cleaning it of all unwanted substances.
That area thats reacted is most likely where your hand's touched it and left greasy deposits.

you saying i got greasy fingers??? :D

only needs a quick sand and a respray on the section... just a shame its not gonna happen between now and nunny.... the weathers shit :(

and ive got to respray my sideskirts...
 
Nice input joe.

Panel wipe clears MOST things.

However there CAN be a few factors simply out of your control. From a painters point of vue.. Anything has a possibility of reacting.. Esp when things have been painted Since the factory.

Aerosols also are a nightmare at times.

Halfords paint should be AVOIDED AT ALL COSTS..

Do a quick Yellow pages search for your nearest paint suppliers.. They are full of advice and the 'paint match' systems they use are 10x times better. Not just a better match.

Better coverage,
Better atomisation ( leading to a better finish )
Better consistancy ( reducing chance of runs )

Massivly less re-active than halfods or motorworld shit.

Alternativly, nip in to a place like ours and blag a quick blow over of your part, for the price of a few beers.
 
what kind of reaction, what's it look like?

as above prep n cleaning, but also how cold was it when/where you sprayed? pretty cold at the mo especially up your way - thats one thing stoppin redoin mine at the minute, i need a nice warm garge somewhere :lol:

well aware halfords paint is crap, but i have never had a problem with there primer, i know it may be small beer but i have sprayed 3 bumpers, a plate surround, sideskirts, a grille and 4 wheels and never had a problem like this.

i do go to a proper paint shop for my base colour.

so i guess i gotta sand this right back to the original colour it was then?

its the splitter i got from you kristian, i think you will agree it hasnt been painted since the factory?

also craig, spraying in the garage with a propane heater

That splitter is definatly factory..

You can paint 100 things and then one will react without warning suddenly..

...:eek:

This is another reason for such high prices for painting.

Ive seen 'crackling' paint before.. INC primer.

Id put money on the paint underneath not having had time to cure, and the primer is eating into it. It deyhdrates the paint you are applying.. It SHRINKS, and the cracks up.. showing up the color underneath.

Best bet, if its possible within reason. Is to leave it until you can sand it, give it a rub. no need to rub it back to the original base.

Theres two things though. Usually when this happens it takes extra long for the concoction on the part to fully cure. Sanding it seems to peel away the paint in places. paint turns putty like.

Also it leaves the surface lumpy. so rather than sand the fuck out of it. get some fresah thick primer filler on it, and sand that back.

A DA sander is ideal.. cuts down the sanding time and effort.

hope this helps bud.
 
you could also be trying to dry it top quickly!

if your putting the heat directly onto the panel!

this will cause a shrinking affect aswell!

even pro painters of 30 years still get reactions at times! there is too many things that can cause something to go wrong!

you can only minimise and reduce the chances you can never stop a reaction happening at all!

sound advice from K there - as said only thing i would personally add is if you were directing the heat straight at the panel!
 
i was a bit :( Just wanted it to dry.. gonna have to re do it now... just not gonna have time between now and nunny... my fault in the end just got to do the skirts before nunny or my cars gonna look shit
