hi had a bump and as a result ended up with a blue bonnet on a white mk2, it wasn't the best of bonnets but to say it was my first time spraying anything i thought i did a damm goo job! :grin: but i got carried away and ended up giving it 4 coats of primer and 6 coats of alpine white and although i did sand the primer smooth i have been left with a grainy bonnet. it's got a rough finish because of the spraying, how can i smooth this out to end up with a slick finish? my dad said get a bit of wet andd dry on the go and lightly sand it then give it a good polish but i dont want to destroy my fantastic work :laugh:!! what do others do, and is my dad off his rocker or is it sence?
cheers

what you need to do is get hold of some 2000 superfine wet and dry and sand the paint work down with plenty of sopy water,cheking as youdo it.dry the area when it is flat with no shiny bits moove on to the next bit,use a circular motion when sanding.when the bonet is all flat you then need to buf it with a buffer.take cere not to go through the paint when doing this. buffing will bring the shine back to your bonet :smiley:
-
If you haven't got a buffer get some cutting paste (Fram halfords etc) and then a good tcut and and a polish and it should come up a treat! Sound slike you've plenty of paint on so lots of room to cut back without fear of going through the paint.

have you got any clearcoat on this?
-
i would have thought you would need a laquer coat which should sort things out :undecided: i would take it back a little too before the clear coat
-
no i've not put a clear coat on yet i was going to sort this out first, then go with the clear. for buffering it up i've got one of these:

so wet and drying it is the right move then, if i used the 2000 grade paper is that a bit too fine i was thinking more like 1000 grade or would that just take it down too much? then would the buffer thats above do with a bit of t-cut and polish to bring the shine back? cheers

1000 grade is to harsh,if you use that then buff it you will still see sanding marks in the paint.insted of t cut use rubbing compound [G3] and the buffer needs to have a sponge head on it.

hit the nail on the head which I was going to say next

and that ain't gonna get you too far... you'd be better off borrowing a decent machine polisher from someone if you can find one..
