Title: Paint reaction
Post by: Lincs niva on July 13, 2007, 20:06:58

Ok ive just made my new rear bumper from 3x3 box section look's good aswell.

Ive cleanded it all down with paint thinner's to remove any grease etc.
Put a nice covering of primer on let that dry for a couple of hours went to put a top coat of black on excellent no problems so far.Started on the second coat about 1 hour later which has now dryed only it's left a light covering of grease over the surface with white specs dotted all over it.

Im using the rattle can's you buy from the local motor factors..

Any ideas why it has reacted???????

Cheers Gav

Im quite sure we havent waxed or polished a car in there.However we have done quite alot of grinding and welding..

As far as im aware i removed all the thinner's prior to painting..

Im going to wet and dry it again tommorow clean up then see if it takes a coat of paint :evil:

Did you wipe it down with Pannel Wipe before putting the paint on?

Check tour primer and top coat are compatible, I have seen all sort of weird and wonderful things happen when enamel/cellulose/2 pack are used together :lol:

Heat your paint till it's warm and pre warm the bumper.

Spray your bumper and then a card board box or something.

Wait till your finger stops sliding across the paint on the box and becomes tacky.

Then apply your next coat of paint repeat till you get the final coat on and use 70% thinners on that one to really give mirror finish.


Good luck post results.
