Front Bumper Prep

GregorFuk · 02-02-2015, 03:11 PM

So, I’m about to get my front bumper re-sprayed but on looking at it it’s clear this won’t be the first time it’s been sprayed, or second, or third, or fourth or……. You catch my drift, it’s thick with paint. So before putting it down for yet another coat of paint it seems like it might be a good idea to take some of the previous layers off.

Has anybody done this before? Do they have any tips? Is the whole idea a big no, no? Is any sort of media blasting safe? Or is the only option to roll up my sleeves and get busy with some sand paper?

Cheers

Gregor

good question......will be interested to hear what the others say that have done this.

I'm afraid that my response is one of those useless ones which frequent BB's, however, I do have some expensive experience here.

After wanting to secure a second front bumper for my car I came across a genuine one that required a small amount of remedial work to correct a few cracks and bits and bobs to get it perfect before respraying.

The bodyshop that did the work for me said that the bumper itself is very strong and of a high quality. They found there to be a few finer, potentially more fragile area's, however, around the carbon fibre joins and specifically on the clips where the front plastic radiator protector grill attaches to the bumper.

They stripped it back to bare before respraying and had no issues. So as I say this is a bit useless as I do not know what method they used to remove the paint, but as they are a 'normal' local repair garage I'd stay it was a standard one.

They did laugh a lot at the price I paid for my non perfect front bumper (£2000) and even more so at the near £4000 for a brand new one.

Get your sanding disc out, having seen more than enough paint jobs on the race car.... Sand back, gives you chance to sort any imperfections. Primer then paint

Don't just use any sand paper ..!!

Easiest, take to paint shop you trust, £200/350 should get you a lovely looking bumper, depending how bad it is.

Sanding it back is best
Removing the old coats of paint that builds up over the years can cause problems
also less paint on it makes it less likely to chip easy

Here's one to practice on:

Great investment shimmy worth more than Gold at the moment
They stopped making the MG ZR rear bumper and when it had a small bump
they were wrighting the car off if the CSL is the same your bumper will be worth a fortune
