Having done this on other vehicle before, I would suggest you remove all bushes etc. before the sandblasting.

I would also suggest you mask any areas you don't want painting yourself, unless you trust your painter to do a neat job.

Are you painting or powder coating?

Hello, I think powder coating because is a professional firm that do this job for me, for mask area, if I remove all removable parts I think that remain really small area to mask.
Thanks a lot!

Agreed on removal of bushes before blasting - be careful to protect anything you cannot remove that isnt being blasted.

Get a sample of work from powder coating place and make sure you are happy with how robust the finish is - like hitting it with hammer, stones etc... Do not discount a treatment of POR15 and suitable top coat as this gives an even tougher finish than many powder coats. The P in POR stands for permanent - when applied correctly on derusted, freshly blasted surface.

So for you Paul the best for paint is use POR15?
Thanks!

Yes - but get some thoughts from professional painters. It is a well respected product in the US and UK classic car / restoration scene. It is also well liked in marine applications as well from what I heard. I have used it myself on subframes etc and it is amazing. You can get a good finish by careful hand painting but spraying it would yield perfection.

it is not friendly stuff to spray so be careful.

I hope that professional painters can do it without problems.

With the factory that made this work we have find the correct colour and is a semigloss black.
