mapping ? do I take you mean the sanded edges have reacted ?
i did it this way as i had looked on here and red this .
Filling a painted surface
It's common advice to strip a panel to bare metal prior to filling, but I don't generally find myself doing this. Modern fillers will stick to most paints with a sand paper keyed finish. The photo shows a dent I didn't spot earlier.
The main risk is paint sinkage and edging, especially when using cellulose paints. New paint will be absorbed into the filler and surrounding paint at different rates, and the dried paint will end up with an edge at the edge of the filler.
To minimise edging I'll prep the paint before filler with 240 grit sandpaper and finish the filler and surrounding paint with 400 grit before over-painting. This also reduces sandpaper scoring which looks really ugly when it shows up in finished paint.
And i`m not haveing a go here i just need the help please people.

possibly, I take it you are using cellulose primer, try flatting back enough to get rid of the affected primer and re-apply the primer but using quite a few light coats letting each coat dry before the next, you need to get the paint on without a lot of thinner sitting there softening the paint below so build it up slowly flatting between coats
Thanks im on rattle cans just to protect repairs at the moment hopeing to sand all the car down this weekend and get the spray guns out to spot prime and then full pass of car then top coat and so on . is the rattle can adding to the maping maybe.

gotta say I hate aerosols they give a terrible spray pattern, primer its self doesn't really protect a repair as primer is pourous, as for priming you don't need to do the full car only the repairs, just don't go heavy with the primer, if it still reacts try some different paint from the gun
Thanks again i will get my guns out then and stop messing about .

Or is it the fee a farmer charges to tow some idiot out who followed the sat nav too literally down that track that really doesn't look like a thoroughfare?
You really ought to be priming with epoxy mate, once set it resists water and so you can take as long as you like to finish the job with no problems, we have all seen cars on the road with the panel in primer that the bloke never got round to top coating and they are always rusting because normal primer is porus, epoxy primer isn't and will protect the repairs
Thanks all cars painted know and for my first go i think ive done a good job
well second go really as me and my mate had to rub it all back again as i screwed up on the clear coat . Picked up the 1.8 tip gun not the 1,4 gun and i put to much clear on
but it was super smooth when finshed.
Just need to buff it know any tip people and how do you all buff the hard to reach places like the door jams where the buffer can`t get in
Thanks again all cheers

what are you using to buff it ? it should be a proper machine polisher anything that spins too fast will ruin the paint
