ive just re sprayed my 4i in Strato Silver, once i put the laquer on i noticed a small reaction on one of the rear wings.

i rubbed it back down and used primer filler but the reaction was still showing, so i rubbed it back further onto the original filler over my welds when replacing the rear arch.

the reaction is still there so i put a skim of fine Surface filler over the top hoping to seal it in, but its still there the moment i put primer filler over the top.

has anyone got any ideas how i can get rid of it as ive got to have the car out of the workshop by next friday and im stumpped.

cheers

 

don`t know what paint ur using but a while ago u could get isolator so paint didn`t react

just an idea like

 

some primer filler paint is not compatible, try sticking to same supplier for all paints

Sometimes this i difficult

Good luck

 

cheers guys, i solved it with a skim of fine surface filler

but its come up in another place now

 

I would say you are putting the base coat on too wet or over thinned

 

i did a 50/50 mix on the base coat was that right?

Its turned out OK now but some areas of the laquer im struggling to get a good finish on so im hoping it will polish up.

 

50/50 is ok, but if you didnt prime the whole 1/4 or rubbed through the primer to show edges during prep, these will be the areas you had a crazing effect... in this instance I would thin a little less... its the solvent in the thinners, I guess you arent using water??

I also hope thats not the full extent of masking in that pic??

 

ive painted the whole car so yeah that was the masking at that time,.

solvent, thiners water?

i used 2k thinners mixed with the base coat and laquer and whilst wet sanding i used a water/fairy liquid mix, was that ok or have i done a big no no

its not a mint paintjob but it was my first time and didnt have much help/advice at the time so ive just done my best.

 

Is the basecoat solvent based or water based? I guess solvent

I wouldnt use 2k thinners in solvent basecoat (unless it specifically specified ie ICI )

what ratio of hardner thinners went into the Clear?

Also fairy liquid in prep process is a big no no
