Striping Powder Coating
How do you do it?
I've had my Roll Bar powder coated and now want to weld in a diagonal bar for the 4 points to fix to, but how do I strip it off?

its easy to strip off small parts, but big parts would be difficult, for smaller parts I would stick it in a closed bin with acetone (so it cant
evaporate) the powdercoating will turn to gell and comes off easily.

Has anyone tried grit blasting? I plan to get my Luego chassis re-painted due to the fact that there are bubles in it in places possibly where the
surface was not clean when painted the first time. I spoke to a local company and they sat that it will come off with grit blasting. They plan to 50
micron metal spray and then new powder coat.

powder coating is a process, not a type of paint. How easy it is to get off will depend on the paint type.....
i had my bike frame powder coated by a specialist bike painter, and it seems as delicate as any other paint.
its not an invincible protection method.

When I have had things powdercoated before (wind vaines, gates, stage sets etc) Ive always been able to cut it with a craft knife (stanley knife) or a
hot knife.
Think I always get a fairly shallow coat though.
<afterthought>
Or am I thinging of Plasticoating?

Do you want to take it all off or just around the welds?
To do it all, assuming you can take the bar off, get it shotblasted. Small areas, heatgun and scraper followed by soft sanding disc in the grinder.

Although there are a number of types of powder coating materials - it is fixed to the part by heating it up and allowing the powder to melt and
combine. Would it not therefore be possible to heat it back up to soften it and then scape it back off - use a heat gun paint stripper or similar.
Some final sanding / refinishing may be required but I should think it would get the bulk off.
I imagine the epoxy based coatings would be the most difficult to remove.
Has anyone ever tried this ?????

Bearing in mind it is on a part supplied and powder coated by Tiger.

It was not powdercoated by Tiger, I didn't give them any more money than I had to!

pretty easy when it's nice and warm. Just like stripping paint with the hot air gun and scraper.
