Prepping shells

[eyeayen]

So whenever I've done this before I've been working in a bodyshop and had everything to my disposal. Now, about to start again at home, in my garage, I've sold all my old gear and was just wondering...

I know people say they don't bother but I've always lightly scuffed the inside of the shell I'm doing to give the paint a key to stick to with a used piece of scotch brite or something.

Does anyone else do this or am I just being to precious about it and wasting my time ?

I've always done it, also made sure the shell is very clean too

I just wash them with washing up liquid and water. Have never scuffed them.
But...I guess it never hurts if you wish to.

I stick to scouring with a coarse wire wool, just be cautious when it comes to chrome though as the effect will diminish if the area which is to be painted with chrome is scoured.

Same as Jon, I don't bother. A good wash with warm soapy water does the trick.

Cheers guys. Thanks for the heads up. I think for my own piece of mind I'll carry on doing it. I don't really like chrome ( I know I'm in the minority here ! ) but I figured it would do that. When I used to prep a normal crash helmet I'd use 800 wet n dry, then when it was finished I'd flat the lacquer with 2000 before polish. If I was prepping a helmet for Chroming, the people that did it specified it was prepped with 2000... Bit of a difference. I always had problems with it and that's why I guess I don't like it. I have bought some off Jon though to back candies with on a new Creme Egg job.

Anyway, I've derailed me own thread here any other thoughts on scuffing greatly appreciated.

Thanks for your input though chaps

Never scuffed, it dulls the finish down a little, as long as you was with fairy liquid and rinse with piping hot water, then liquid mask right on top straight after drying, never had an issue.
