side sill soda blasting

[JST2CRZY]

I'm having the sills repainted and the shop suggested that soda blasting might be an alternative to chemical stripping of the paint. Anyone tried this?

Thanks

They're aluminum. Might be too soft for that.

Have not done had it done to side sills but have had it done to other aluminum parts. It is the best alternative to stripping them. It leaves the surface smooth and not grainy like other medias do

What's the negatives of chemical stripping ?

Just sand them and repaint them. That's what I did. There is no need to strip them down to the bare metal.

if they have pin holes in them you have to strip to bare metal and weld all pin holes you be as good as new

Soda blasting will do a better job and is much quicker

X2. No need to strip. If there is no issues with the paint lifting, sand and paint.

Well, I have done it both ways...sanding to bare metal and repainting over existing paint. THe issue I had with simply sanding/repaining over the old is the rate of expansion the new paint had over the old...it ended up cracking (even with flex agent). When I totally removed to bare metal, I have had no issue with the paint. Looks great. So even though stripping/blasting to bare metal is more work, in my case it was necessary.

I once had an entire vehicle soda blasted. Unlike sand blastting that creates alot of heat, soda blasting can be done on fragile parts like hoods etc and wont warp them from heat.

Soda blasting is basically baking soda at high pressure.

Not sure about the side sills but I dont forsee an issue as long as the operator has a brain.

My experience with soda( Never on a Viper) is it cleans aluminum very well with No damage, However it must be washed extremely well if there is any metal overlapping as the soda will sneak under the overlapping metal and it works its way out when paint is applied and then the paint flakes off. Just don't blow it off, you must pressure wash the item after blasting, Also you might want to take a little rough sandpaper and scuff it up a bit as the soda blasting is very smooth.
