I need help! I had the paint removed on my 80 Volare with the "dustless" method and the guy warped the hood. I need a hood! Help!
I can understand that. For $1,000 – I want close to perfection.
There are three kinds of blasting out there and I’m quite familiar with two of them.
One is blasting with sand – which is not very good for most automotive items. I’ve used it on housing and concrete repairs.
Next one is with glass beads. Sometimes referred to bead blasting. Glass beads work great for metal brackets and engine components – just as long as items are thicker and are washed well after cleaning. Remaining glass beads might be as bad as leaving a large handful of dirt inside of a fresh engine rebuild. I’ve spent numerous hours/days/weeks using bead blasting.
Lastly is soda blasting. Not worked with this one before – but is by far the the best for automotive sheet metal.
Sand is way-to-abrasive for most anything automotive related.
Glass bead is great for iron, steel (brackets), pulleys, etc. – but is a bit harsh on aluminum and can cause hot spots (ie: warpage) on sheet metal.
All use compressed air – with compressed air there is a big need to have air/water filters in them to remove the water moisture and oil.
I’ve not heard of an additive like you mentioned – but I’ve not done any kind of blasting for many years.
I am surprised someone glass bead blasted a car and expected body panels not to warp!

Cormac - no offence meant or intended.
Blasting, is not (until now?) dust-free and I was trying to understand how.
Thank you for explaining.
