I need some advice please. My spoiler had paint cracks so I sanded down the paint and used P38 filler. I then smoothed it down with sandpaper as per norm. However there are hair line cracks in the filler which shows up when primed. Can anyone recommend any sort of putty mix that I can put on top of the filler for a smooth even finish ? Where can they be purchased and how much ? This is the first time I ever done this and I am getting there slowly but surely.

 

Thanking you all in advance.

Knifing putty, should be able to get it from halfrauds, if it's cracking bad it wont be long for it to come right through.

are you respraying the original nissan foam/sponge spoiler m8?

if so and water has got into it your only ever going to be able to do a temp' job, it WILL crack again and very quickly, if you want to keep that style?

then better going for the fibreglass replacement

ehh, I am ashamed to say yes....

thought I would save a few bucks until I had enough money for the big boy kits...

don't tell anyone though....have got an image to keep...

sssshhhh

i had a complete colour change and the bubbles and cracks are coming through only 3 months later :cry:

need a new spoiler dood.

You can,t really re-finish sponge spoilers with any lasting results :headvswal as already said your better off replacing it :dance:
