I have repaired the deteriorated areas on the bumper covers using a flex-fill epoxy filler. After feathering out the areas, I am not too sure how well they will look once paint is applied.

On steel panels I always go over my repairs with epoxy primer, then Featherfill and/or a urethane primer-surfacer to get it flat.

I plan to use epoxy primer first as I understand it will adhere very well to a urethane bumper. Is there an equivalent high-build sprayable product that can be used here? I have heard of high build epoxy primers.

My reasoning is I would just like to be able to block the entire surface to ensure it's flat.

Any thoughts?

 

Look to see if the brand primer you want to use has a flex additive like this, https://products.axaltacs.com/dcat/u...uct/4950S.html
