Question Blending Paint

Alright everyone I need some help, anyone who has done this or is good with auto painting techniques can help me out here. I am gonna be painting my ss bumper soon and need to know how to blend the paint and clear coat with the rest of the car..the bumper was already Victory red but it needed repaired and rather than spot painting all over the place I'm repainting the whole thing. Would it be easier if I blend the paint within the bumper or easier if I blend it through the fender..the sides of the bumper that will be touching the car are fine so I was thinking it would be easier to blend it that way..but I'm not sure how.

Thanks in advance for any help or advice

well professionals require* about 6 inches from furthest primer spot to edge of panel to blend, (*we'll use 4" cause we're cheap).

if you've never done it before, I would make sure you have at least eight inches and just blend within the panel. Otherwise you are going to need a significantly greater amount of clear coat to re clear the fenders and possibly hood. not to mention the headache of buffing everything you clear to get it back to a factory finish.

I would just repaint the whole bumper and nothing else. no blending. Just make sure the color matches correctly and you will be good. If you look close none of the plastic bumpers match the metal panels on GM cars perfectly anyway.

i work for a company that uses ppg industrial coatings and one of our reps came in and i was talking to him about painting this. he said give him a call and hell hook me up. the body shop im going to to get the paint is more than likely gonna use a matching gun on my car anyways.

I agree... Painting metal & plastic yields different shades (though slight) even from the factory. Paint your bumper cover only and do not mess with surrounding panels. You can always repaint your cover again but don't mess with something that is OK to start with!!

That's what I was thinking...I went out and got rustoleum aircraft remover...that works amazingly..especially on a factory finish..the paint literally shrinks and comes right off the surface...let it sit for ten minutes and you just wash it off with water...it's awesome

if you used a stripper don't forget to use an adhesion promoter before you paint.

actually if ur stripping the paint off with paint remover u should sand the plastic, spray plastics adhesion promoter and prime it first...the reason being (been doing this for a living for the past 5 years and I've seen it happen) if u don't get all the stripper off it will bubble ur paint....as for blending just do the corners of ur bumpers if there's still room after ur wetbed and clear.....but I wouldn't worry about blending since most bumpers don't match anyways ( mine don't, its silver and the gm gold ones don't either cuz they're painted at different factories than the car)...if u do decide to blend don't use sandpaper to prep where u are gonna blend cuz it'll show sand scartches...use yellow paste (dupont, not sure what color it is for other companies) and a gold or gray scotch-brite pad....probably just easier not to blend lol...hope I was of some assistance and good luck \m/
