my suggestion is that try mirrors first... theyre lot smaller and when you learn, bumber will look even better than mirrors! cos its quite big area if you havent done it before...

just telling cos when i did it first time i just started from bigger to smaller...


...and mirrors did look lot better!!

but when its last primer, make it properly*more than o quick one*, will be better surface.

ive used for cleaning pure alcohol or xylen,depending on the material.

Adam - DO NOT USE LAQUER. Glacier white is a solid, and usin laquer will just make all ur hard work go to pot, turning it cloudy and crap.

Plastic Primer
White Primer
Glacier White Paint (preferably vaux stuff - best finish i've found)

Then Carefully T-cut it down to a shiny pro finish.

Just remember the final product will reflect the time and effort u put in. When u think u've sanded enough.........TRUST ME U HAVENT. U want it so smooth that it almost turns into a shiney reflective surface!!

even tho the bottom half is already smooth and painted, sand down to get rid of scratches etc. Fill any cracks or defects properly.

Oh and have i said yet, SANDING, SANDING, MORE SANDING - and take ur time

honestly

To be totally honest with u, and no disrespect to u, but u will end up respraying it more than once coz of insufficient sanding.

Not being rude tho, coz i did it. And when i say i did it, i messed up big time. Thought everything was lovely perfect, got my bonnet sprayed, and it was a waste of 80 it cost to get me bonnet sprayed.



u've bin warned mate, the process u'll b sayin in ur sleep afterwards

filler, sand paper, filler, sandpaper, 1200 grit..droool....... lol

Matt
