Sealers and ABS plastic

I purchased all my paint products from www.thecoatingstore.com for my motorcycle plastics. The primer I bought does not have the greatest build up when it comes to hiding much of anything. My concern is I have done a bit of bodywork on a couple cracks and Im afraid the "putty"" will come through. I will be doing a bc/cc, solid white. I am considering a sealer but wanted to get some opinions first. The primer I bought is linked below.

Do you think the sealer is a good idea or needed?
If so, should I go with white or another light color to see coverage on the plastics?

Any and opinions are appreciated...

Are you working over paint or you working with a new ABS parts if it is new plastic then you will need to clean the surface with a plastic cleaner and primer within 15 minutes and use a adhesive permotor I believe you should be ok with the primer you have

These are already painted OEM plastics....I have completed the bodywork, currently sanding down all the existing paint with 320, then will be spraying primer onto surface...From there Im undecided on my next step

I wouldnt sand all the way to the plastic if I didnt have to but if you do I would use a plastic cleaner before I applyed any primer then my next move would be prime and wetsand with 800 and then you should be ready to seal and paint

only places Im going to the ABS is where I have had to do bodywork...The rest is being scuffed only...So you do recommend a sealer before the base??

I always use a sealer it helps seal you work and also helps with coverage

Always use a primer/surfacer/sealer on abs, the stuff 'rolls' when sanding let alone base will lift and creep and show at paint edges...



I recomend a skim of a 2 part finishing putty coat out there into the good paint roughed with 180 and don't make the common mistake and trust that primer will fill. It's a big risk and not worth taking . Use a 2 part epoxy primer/surfacer on top
Heres restoration on parts that are no longer available you might get a kick out of...
