just so you know some of the effort involved here is what i do with my helmets , Fiberglass of course ,
after all stripping i rub down with 180 grit paper , as helmets usually have lots of stickers under the lacquer this helps get rid of some of the sticker lines/ ridges ,
Then i give it three coats of high build primer and leave to dry
I then spray the helmet with a can of normal black aerosol spray , after a few minutes i then rub the helmet down again with 400 grit , as i have painted it black , the black paint sits in any rigdes or small imperfections so i can see to smooth it more ,
when smooth i give it two wet coats of high build primer again
When this is dry i rub the whole helmet down wet with 800 wet n dry
i then paint it the desired colour and laquer it, this is because when i am applying decals and "touching" the basecoat i do not risk marking or contaminating it .
i then rub it down again with 1500 grit paper to key it and so there is no shine ,
this enables the decals to be applied wet so they can be moved into position ,
when this is all done and i am happy with the result i will then lightly scuff over the decals with grey scotchbrite so the laquer sticks to them .And then finally apply two good coats of laquer .
basically you have to be thorough to make a good job , things to bear in mind is that if you dont undercoat properly , if there is only the slightest part of a lightly sanded bare decal showing it will pickle the paint up ,, i have found out the hard way , also paint/laquer will not stick to anything that is shiny ,this is why i allways lightly scuff the decals , so many times have i seen highly polished streetfighters and rebuilds only to see the lacquer bubbling over the decals
