righto, i have a mk3 bootlid withe the number plate reces welded so i have about 5-10mm to fill and its done apart from a bit on the right side were dopy me sanded a bit to much and it needs one more tiny layer now, doh!!but the wiper blade and boot lock hole are a night mare, i have fiberglasd behind it (it was to hard to weld in that tiny space!) but every time i put a bit of filler over the top i sand it down it feels smooth as a **** bit on closer inspection there are two or three tiny lil holes were filler has had a buble in it or somthing, how do i do this with out the bubles!!! pls help me

 

firstly take the fibreglass out cus mate thats just gonna fall out when u shut the boot , and second , keep goin over the filler until there are no little dents in it, simple lol , cheers mark.

 

ok dood sounds good but how do i stop it from sinking?

 

its gotta be sinking somewhere mate , depends how and what u are using, dont use cheap filler cus that will sink like a bitch , and dont rub it down with wet and dry thats wet because that will cause it to sink too, also leave it for at least 12 hours before u rub it down otherwise there aint no point. mark.

 

u have to weld up holes otherwise it will always sink. fiblreglass isnt enuff

 

use 'stopper' (cellulose putty) to fill pin holes before priming and painting.
