Is it OK to leave 2 months between coats?

[Joseph Peace]

Hello all.

I've got a job which I painted black a couple of months ago. I now want to finish the job with a design. It has been out on the road so I washed it and rinsed super thoroughly.

The design is yellow and red and as I'm going over black I thought it best to use grey primer first or I'll need gallons of paint as I'm using celly.

Can I spray the primer straight onto the black? Will it stick OK? Should I give it a wipe with thinners to be totally sure of cleanliness or will it have cured so much I now need to use wet and dry?

Sorry to seem so clueless but I really don't want to mess this up!

Ta. Joe.

After 2 months I would flat with 400-600 prime and flat again, before top coat

I was thinking that's what I might have to do.

So, how long can you realistically leave it and not have to flat it before putting the next coat on? I'm going to be doing some masking so obviously it needs to be dry before masking but not too cured so the next coat bonds ok? Am I thinking along the right lines?

dont need to prime on top of good paint

sand with a scotch pad or 800-1000 wet , then mask up and paint

as steveo
dont need to prime and if you do you will risk showing an edge of grey primer in the design

I don't need to prime I know but I'm using yellow over black. If I use the primer I'll need a lot less yellow to get a good solid colour.

There will be a blue pinstripe between the yellow and black so this will hide any grey edge.

You could feather the edge of the primer and re-mask before applying the yellow, would also be a dry run to see if its to your liking before using up your colour.
