so paint is good above 68'F/20'c i hear... how about primer? anyone know? i can't find info - it's way under that right now like 55/12

i'm going to use a brush again, this will be interesting (to me at least)... preview anyone?

'krud kutter' acid prep seems to work really well btw...

OMG! You'd be better off taking it a bodyshop and having the whole panel sanded back, prepped and resprayed. That damaged area is way to large to 'repair'.

HTH,

what are you nuts?


j/k i'm killing myself reading your replies - yah i know it's really bad but i've got some paint left over (not enough for the whole thing) from my grill job and i thought i'd try it seeing as another job i did turned out a hundred times better than i thought it would. if it doesn't work it already looked awful - the rest of the car isn't brand new either (tho it is pretty clean)- there's a beautiful dent on the front end of the hood that i'm going to leave as is it kind of gives it personality.... may i remind you this is a winter driven 525i auto and it's going to get its ass kicked in a couple months anyway... need a couple tires and i love it but i'm sick of spending money on it (for now) - at least there's no rust! :D

i bet it turns out better than you think it will all the same... we'll see i don't know...

so... still wondering about what temperature you can put primer on....


edit- oh i should explain i'm going to prime then putty then prime again have a little faith guys i'll make it smooth - you saw my grill (http://www.bimmernut.com/forum/showthread.php?p=310173#poststop) right?
it wasn't so bad i don't think... by my standards anyway...

Treat it as paint, same ambient temperatures apply.

I had to sand down and prime my baby earlier this year. Drove around with green epoxy primer for two months! My kids hated it...but it did give it personality.

Keep at it. Paint some flames on the hood, this way we won't see the difference ! :D

We should see some warmer days yet before November methinks.

Tim, thats pretty F@#ed up LMAO!!! Okay with primer in cold weather.. you are gonna bondo that stuff up no? Anyways just use clean up thinner/reducer IE: fast reducer/thinner, want it to dry fast in cool weather. In cool weather take more time between coats and dry time before the paint or you will have a build up of solvent under the outer coats and will lead to bubbling and or peeling nomatter how or what grit you leave the lower coats. Edit: Especially if you layer them craters with some bondo.

Hope you followed that if not PM me... man thats a mess did anyone mention that?

LMAO :D :D :D

I can appreciate your methods as I've 'touched up' hoods in the past. Maybe you are planning to do this, but I thought I'd mention that a large improvement would be made if you sanded, primed, painted etc. in a line that follows the curve of the hood. It wouldn't be much more work and would also make application easier as you wouldn't be hopping from patch to patch.

Go for it,

Dave

noted and appreciated... i'm weighing this vs blending it ... there's no way it will be perfect and i'm wondering if blotches will be slightly more subtle than a straight line if you follow...

K, id personally clean up the paint with fine paper after your bondo method. when ready try to feather the fine sanding about an inch beyone the destined area but not farther. Dont plaster it to that point just feather the area you are fixing. My god a big tape line be as bad as non sanded bondo. it is real tough to refrain from plastering to the tape line but is possible. A clear coat will guarantee an ogly result... feather and be subtle with it. use fast thiner/reducer in cold temps... take a week or 2 to wheel the shine back, cold weather requires it.
