What is the most painless way to do this.

I already spent a lot of time on this, after removing the dummy air intakes and stripping them laboriously with all the fine detail they have with the indentations etc. My mistake was to use the MP Argent silver paint which was like water and ran everywhere. Now I really need to strip them again, plus do the main grill. Part of the grill is bare black plastic, so that is a factor too. Can the bare plastic be made to look good (e.g. with plastic media blasting, or soda, or something?) or it is going to need painting?

I'll pay someone to do it if it is an effective method and low risk (don't want them ruining it), or just get on with it myself if that is the best route - other than spending weeks on it.

I'd really appreciate any advice, I want to get back into this tomorrow......

I have no real world experience...paint doesn't like brake fluid....so the paint may come off with it but I don't know what type of residue or damage it may leave to the plastic underneath

I'm thinking just regular sand paper and do it carefully by hand. It don't need to be completely stripped, just smooth so the new paint looks good.

I painted mine in 2005 and it is holding up well.

I may be able to strip the paint with my heated pressure washer without hurting the plastic, it would be a trial and error thing.

But by the time and money it would take to send it somewhere, you could get good start on it by hand for free.

I used Totally Auto argent and liked it. I should have used more coats since it's getting thin again. I can't help you strip it, but I agree with above comments in just sanding smooth. Argent is a little rough anyway.

Actually I did the rear panel already and for the textured argent part I thoroughly cleaned and scuffed the original (which was in pretty decent shape) and painted over it with the Totally Auto stuff - very happy with the result (to be clear the useless MP paint was the non-textured silver)

But for the front the non-textured silver paint especially is engrained dirt, which might need more complete removal - but I can def try to sand it. But stripping the "air intakes" needs something other than sanding. And the bare black plastic I think will need more than cleaning, and sanding won't work by itself, so it's either paint that black if necessary (I'd rather not) or find a way to revitalise it......

I sand blast all my plastic grills, even 71 cuda grills. Just lower the pressure down to about 80psi, and have at it. works great. yes you will have to paint the black area, unless you want to try and use polish to buff it back to a shine.

Don't use a hot water pressure washer....1000 psi of hot water will blow that grill to pieces.
