Body aluminum - sandblast and painting
Posted: Wed Aug 18, 2021 10:48 pm
Hi all;
I have a pre-loved tailgate and winch space cover plate I intend to mount up on my S3. Rightly or wrongly, I sandblasted them this week at Blast-it here in Vic while working on a few other projects. Not having much experience on body work in general, or aluminium painting specifically, am looking for tips on the prep and paint process. I have heard alu is tough to get paint to bond to, and a tailgate is a spot where I am keen to have some resiliency to scratches and regular use. I have a rattle-can done up with matching paint by a local shop, and am ready to tackle the prep and paint. Do I need to pre-sand at a high grit to get a smother finish? Recommendations on primer, steps between paint coats?
Thanks in advance
